Doors are a significant object for the visually impaired and robots to enter and exit buildings. Although the accuracy of door detection is reported high in indoor scenes, it has become a difficult problem in outdoor scenes in computer vision. The reason may lie in the fact that such properties of a simple ordinary door such as handles, corners, and the gap between the door and the ground may not be visible due to the great variety of doors in outdoor environments. In this paper, we present a vision-based method for detecting building entrances in outdoor images. After extracting the lines and deleting the extra ones, regions between the vertical lines are specified and the features including height, width, location, color, texture and the number of lines inside the regions are obtained. Finally, some additional knowledge such as door existence at the bottom of the image, a reasonable height and width of a door, the difference between color and texture of the doors and those of the neighboring regions, and numerous lines on doors is used to decide on door detection. The method was tested on eTRIMS dataset and our own dataset including doors of houses, apartments, and stores leading to acceptable results. The obtained results show that our approach outperforms comparable state-of-the-art approaches. Manuscript profile

Doors are an important sign for blind people and robots to enter and leave the building. Detection of doors in outdoor environments has become one of the most difficult issues in computer vision; Because usually in outdoor doors, the features of a simple door such as handles, corners and empty space between the door and the floor are not obvious. In this article, a method for detecting doors in outdoor environments is presented. After extracting the lines and removing the extra lines, the area between the vertical lines is formed and the characteristics of each area including height, width, location, color, texture and number of lines inside the area are extracted. Additional knowledge such as the presence of the door at the bottom of the image, the reasonable height and width of the door, and the difference in color and texture of the door with the surrounding area are then used to determine the presence of the door. This method has been tested on our eTRIMS image collection and our image collection, including doors of houses, apartments and shops, and the presented results show the superiority of the proposed method over the previous methods.

The main aim of doing this research was to assess the resilience in Farahzad neighborhood of Tehran. In order to assess resilience in social, economic, and managerial- institutional dimensions, questionnaire method was used and in order to assess physical section, field study and GIS software was used. One of the most important ideas that has been going on in current decade about crisis management and also urban management, is to create resisting cities and cities than can resist various crisis. Urban resilience can be described as the ability of an urban area to resist against dangers such as climate change, accidents, economic and social poorness to resist against them, absorb and adapt them or to avoid them. The thought of resilience in complicated systems such as cities, enables the understanding of mobility and nonlinear relations in such systems. This thinking, in the modern urban zone, the ability to integrate human and ecologic factors in urban systems and understanding their interactions, enables the extension of sustainable strategies according to the identified attractions. Today, mostly cities and settlement societies are created or built in such places that in terms of natural disasters are in danger of various of them and or because of technological advances are in danger of human made accidents. The perspective that has been there in management of accidents and urban management, has been mostly conflicting and decreasing the dangers. About the assessments done on social resilience in Farahzad neighborhood, based on the completed questionnaires, it can be said that the social tendency to participate with an average of 3.94 was ranked first. In second rank, is social ties with neighbors with an average of 3.82 and in third rank is the ability to adapt to tensions and chaos with an average of 3.64. Factors of participation in decision making and level of participation to solve the crisis with 3.55 and 3.46 averages in order, are ranked fourth and fifth. Local understanding of danger with an average of 3.15 is on sixth rank and knowledge and awareness of crisis with average of 2.95 is ranked seventh. Altogether, the sum of social resilience in the studied neighborhood was 3.50 which can be said that the level of social resilience in Farahzad neighborhood is at an average level.

The neighborhood has a special place in Iranian cities and is one of the elements that plays a key role in shaping collective identities. However, the body shapes the city, but beyond it, it repeats the role played in the daily lives of the inhabitants and plays a role in long-term collective memory. They become elements of identity that change in these structures can make fundamental changes to the foundations of the identity of a city. However, today, the neighborhood is no longer of importance and credibility, but with respect to the remaining historical nuclei of the old neighborhoods, it continues to identity in some areas. Urban development plans such as renovation and renovation projects of textiles and worn out sites are among the most important designs and tools that can have a positive or negative impact on neighborhood structures and neighborhood. The purpose of this study was to investigate the impact of urbanization and renovation projects on urbanization in district 10 of Tehran municipality. The present research is based on the applied objective and based on the descriptive-analytical method. The data gathering method was documentary and field study (in the form of a questionnaire, interview). Descriptive statistics (frequency, mean, ...) and inferential statistics (correlation, multivariate regression) were used to analyze the data using spss software as well as content analysis method. To this end, structural, physical, security, economic, and health indicators have been used for neighborhoodism. The results of this study indicate that, despite the fact that the implementation of urban regeneration and renovation projects in terms of structural and physical aspects has had dramatic results in the region, but the impact of these plans on the feeling of belonging to people The local area and local identity have been weak and sometimes caused the lack of trust and sense of belonging to the local community and the surrounding environment, making them unsuccessful in terms of social performance. Overall, evaluating urban drainage projects and projects has not been followed up with studies of its strategies and policies, and has not succeeded in strengthening the foundations of neighborhoodism, and it can even be said that the implementation of these plans has weakened the dimensions of neighborhood and neighborhood status in the social system. .

Newurbanism is an effort to raise traditional urbanization and to adapt it to modern life today. This movment came to the fore in the twentieth centary and latly in the current decade it was considerd and emphasize on by authorities and urbanization experts in our country. The main charictristics of this attitude is being humanist and bolding human roles in our modern-lif cities just as it was noticible before. The purpose of this study is to study conperhensive development, distressed area, pedestrian Attitude of new urbanism in the city of Maraghe. In this context with utilizing the methods of descriptive, analyctice and field study we try to study existing subject and also we have made use of Holdren and shanon antropy methods.the level of antropy in the year 1390 was 1.84 and Ln n = 1.94, and shanon antropy was close to 1.94, this was a sign of physical development that was scattered and uncompressed. In the other hand the result of Holdern antropy showed the development that happened horizontaly. The unending spread of cities in the recent decades has made. Old texture inhabitants abandon and live in cities that have lead to horizontal and ancompressed city development also because of uncompressed development and increase of access roates, use of public and private vechicles has exceeded and coused problems for pedestrian access. The result indicats that the city of maraghe is not matching with the new urbanism. Manuscript profile

Upper parts of Elika carbonate Formation belonging to middle Triassic in central part of structural- sedimentary zone of Alborz in East of Mazandaran province (Savadkuh, Khatirkuh and Kiasar regions) are hosted some of important F-Pb-Ba ore deposits contain of PachiMiana, SheshRudbar, Era(Alikola) and Kamarposht. Based on of field observations in study, main localization of ore bodies within carbonate rocks are as acrostic, irregular, and discordant respect to bedding that are displayed in fractures and/or karstic cavities in the form of vein, lenses and bodies. Mineralogy in studied ore deposits generally is simple and mainly composed of galena, barite, fluorite, calcite and minor sphalerite. Macroscopic and microscopic observations are shown variety of syngenetic and epigenetic structures and textures. Disseminate, stylolite and micro-veinlet textures of galena and calcite with or without other mainly minerals are recognized as syn-genetic textures respect to host rocks. Epigenetic structures and textures as open space filling type such as vein-veinlet, zebra, lamination, primary replacement and colloform are dominant textures of high-grade ores that formed main and economic zones of ore body concentration in deposits. Existence of secondary textures such as curvature and wind in triangle cleavage of coarse-grained galenas and also replacement of galena by cerussite and covellite show deformation and supergene oxidation after the main stage of mineralization. Based on current research, mineralization in F-Ba-Pb ore deposits of central Mazandaran is formed and evolved at two steps (1) primary or syn-diagenetic, and (2) main or epigenetic. According to structural signatures of ore body appearance in deposits environment and also textural evidences in macroscopic and microscopic scales, the main and economic stage of mineralization in studied ore deposits is introduced as epigenetic.

Various diagenetic processes have affected reservoir quality of the Asmari Formation in Ahvaz Oil Field in wells No. 19 with a thickness of 357 meters. It is composed of limestone dolomite, dolomitic limestone, sandy dolomitic limestone, sandstone, siltstone and shale. Study of 1100 thin sections from available cores at this well as well as the well’s numeral data, porosity and permeability of cores, indicates that the most important diagenetic processes is anhydritic cement with different types of textures. It appears as poikilotopic, porefilling and pervasive, nodular, fracture filling, sparce crystals, and evaporite veins. During different steps of diagenesis, these texture show replacement and pore filling porosity that have affected different facies to some degrees. Results of this study show that anhydrite cement occurs mainly in dolomitic and sandstone facies and to some extent, affected the reservoir quality. This is due to the effect of sulphate rich brines during dolomitization. Where the presence of anhydrite cements in limestone facies is sparse and rare, it has little effect on reservoir quality. However, pore filling and pervasive anhydrite texture filling all pore-space in dolograinstone and dolopackstone grain-supported facies during shallow burial intensively reduced reservoir quality. Dissolution of cements at later stage of diagenetic processes (creating secondary porosity) improved reservoir quality. In addition, solution of texture poikilotopic anhydrite in sandstone facies and repercipitated as patchy anhydrite with poikilotopic texture, results in reduction of porosity but it doesn’t make any changes in throat pores. Hence patchy anhydrite with poikilotopic texture that reduces porosity converts the sample from Lucias class 2 to class 1. Manuscript profile

Renovation of worn-out tissues is a necessity for which there is numerous legal and national support at the national and macro levels. According to the annual law, 10% of these tissues must be renovated, and in order to achieve this goal, a role and task will be assigned to all government and public bodies in the form of a regeneration headquarters defined at the national to city levels. In addition to the capacity of the Reconstruction Headquarters, several laws have also stated the need to renovate worn-out structures and have devised instructions and solutions for it, including the Law on Urban Renovation and Development, the Law on Organizing and Supporting the Production and Supply of Housing, and the Law. He noted the support for the rehabilitation, improvement and renovation of worn-out and dysfunctional urban structures. Examining these laws shows that all aspects of worn-out tissue renovation are addressed at the policy level. But the ambiguous point is that despite these rules and the goals that have been set, why the path to goals is slow and in some cases impossible and the field of implementation is facing something different from the field of policy. For this purpose, by examining the laws, domestic and foreign experiences and literature, an attempt has been made to obtain a framework to determine the key measures of the success of modernization projects in the field of implementation. Data analysis has been done by SWOT method and solutions have been presented by strategic planning method. The results obtained from the analysis and interviews completed in this report show a functional difference and goal setting between the actors in the field of modernization and a kind of imbalance in the distribution of resources, roles, inter-agency relations and legally defined expectations and tasks. There is a field of modernization for the actors. Some of the solutions presented in this plan can be defined as the legal position in the Deputy of Planning and Development of Municipalities for offices, defining the legal position in the Deputy of Planning and Development of Municipalities for offices and activating the renovation house The following is the framework of Sarai Mahallat for purposeful activities in the field of tissue modernization.

Identity, culture and related elements are not only conceptual components of urban space but also necessary to create urban space. Accordingly, the city and the public spaces express their thoughts, ideas and the cultural interactions and its form declares their functions and meanings. Urban spaces have provided the basis for people’s participation and interaction and have established a flow of culture, notion, and human experiences so that the presence of human beings in urban spaces leads to dynamism in urban spaces. Squares play a vital role in citizens’ minds and on the other hand, it is a field for the presence of people and their activities, which requires physical and functional continuity in the best way for the appearance of this meaning. The present study aims to apply the descriptive-analytical method using the SWOT matrix and the quantitative strategic planning matrix (QSPM), tries to identify strengths, weaknesses, opportunities and threats and offers practical strategies to deal with weaknesses and threats by using the strengths and opportunities. The main concentration of the present study is on the physical-visual system using operational strategies following the defined strategies to organize the physical and visual system of the historical square of Vijoyeh, Tabriz, which currently lacks its historical and cultural identity. The aim is to restore life to the vital arteries of the historical context along with reviving the original identity of this field, and it is hoped that the presented practical results will be a way to revive similar historical contexts in order to take a step towards protecting the rich cultural of Iran and its historical identity.

A novel approach for steganography cover selection is proposed, based on image texture features and human visual system. Our proposed algorithm employs run length matrix to select a set of appropriate images from an image database and creates their stego version after embedding process. Then, it computes similarity between original images and their stego versions by using structural similarity as image quality metric to select, as the best cover, one image with maximum similarity with its stego. According to the results of comparing our new proposed cover selection algorithm with other steganography methods, it is confirmed that the proposed algorithm is able to increase the stego quality. We also evaluated the robustness of our algorithm over steganalysis methods such as Wavelet based and Block based steganalyses; the experimental results show that the proposed approach decreases the risk of message hiding detection.

Image retrieval is one of the most applicable image processing techniques which have been extensively used. Feature extraction is one of the most important procedures used for interpretation and indexing images in Content-Based Image Retrieval (CBIR) systems. Effective storage, indexing and managing a large number of image collections are critical challenges in computer systems. There are many proposed methods to overcome these problems. However, the rate of image retrieval and speed of retrieval are still interesting fields of researches. In this paper, we propose a new method based on combination of Gabor filter and Walsh transform and Wavelet Pyramid (GWWP). The Crossover Point (CP) of precision and recall are considered as metrics to evaluate and compare different methods. The Obtained results show using GWWP provides better performance in compared to with other methods. Manuscript profile

Counting mitotic figures present in tissue samples from a patient with cancer, plays a crucial role in assessing the patient’s survival chances. In clinical practice, mitotic cells are counted manually by pathologists in order to grade the proliferative activity of breast tumors. However, detecting mitoses under a microscope is a labourious, time-consuming task which can benefit from computer aided diagnosis. In this research we aim to detect mitotic cells present in breast cancer tissue, using only texture and pattern features. To classify cells into mitotic and non-mitotic classes, we use an AdaBoost classifier, an ensemble learning method which uses other (weak) classifiers to construct a strong classifier. 11 different classifiers were used separately as base learners, and their classification performance was recorded. The proposed ensemble classifier is tested on the standard MITOS-ATYPIA-14 dataset, where a pixel window around each cells center was extracted to be used as training data. It was observed that an AdaBoost that used Logistic Regression as its base learner achieved a F1 Score of 0.85 using only texture features as input which shows a significant performance improvement over status quo. It also observed that "Decision Trees" provides the best recall among base classifiers and "Random Forest" has the best Precision. Manuscript profile

The universe is made up of living and non-living beings. Based on its capacity, each of them has a level of life. Human creations, because of the change or stability in the conditions of matter, make it possible discover or create and have the ability to create levels of life. The builders’ attempt to create works and structures which is somewhat close to these characteristics. Characteristics in which the sense of vitality, kindness and other qualitative components are strengthened. Therefore, the research emerges to ask such questions; which classification can be considered in relation to the levels of life in constructions? How has the spatial quality of traditional houses in Yazd achieved success with the presence of life components? The present article seeks to present or propose the concept of life classification in structures in which more properly is expressed the values and characteristics related to the life of structures. Therefore, it seems that this feature is more recognizable in traditional cities. In order to understand it precisely with reference to the historical texture of Yazd city, the patterns of the central courtyard houses, sunken garden and garden house are selected and classified. The research is based on analytical and descriptive method along with documentary and field data collection. Also, in a precise framework, all datas are collected and analyzed based on the principle of induction, and summarized the document. The result shows that, in the traditional houses of Yazd, six general systems related to the category of life can be identified. Life as an empirical thing exists in all beings. It looks like metaphorical, energical, biological, and Spiritual aspects. Finally life as an inspiring idea forms the structure of the research. Manuscript profile

One of the methods which can produce powerful features for texture classification is Local Binary Patterns, LBP. In this paper we propose a method for defect detection in textile fabrics using these features. In the training stage, at first step LBP operator is applied to an image of defect free fabric, pixel by pixel, and the reference feature vector is computed. Then this image is divided into windows and LBP operator is applied on each of these windows. Based on comparison to the reference feature vector a suitable threshold for defect free windows is found. In the detection stage, a test image is divided into windows and using the threshold, defective windows can be detected. The proposed method is gray scale and shift invariant and can be used for defect detection in patterned and plain fabrics. Due to its simplicity online implementation is possible. Manuscript profile

In this paper, two kinds of defects in Golden Delicious apples are recognized: bruise and russet. Russet is divided to two classes: russet in stem-end and russet out of stem-end. Apples are graded into three classes I, II and rejected, according to European standard. To grade the apples, it is necessary to classify apple images into six classes: stem, calyx, bruise, russet in stem-end, russet out of stem-end and healthy. In this method, after pixel-based classification based on RGB color features by a perceptron neural network, correction in classification and stem detection is made. Hue and saturation features are used to correct the image regions classified to bruise. The correction of regions classified to calyx, russet in stem-end and russet out of stem-end is made based on the distance from the gravity center of the stem to the gravity center of each region. This paper presents a new method for defect classification and sub classification of russet to two classes, russet in stem-end and russet out of stem-end. Experimental results of the proposed algorithm show that the correct grading rate of 120 apple images is 81.66%. The grading errors result from misdetection of stem and errors in defect detection.

Ultrasonography is one of the most useful diagnostic tools for human soft tissue and is one of the methods that are in routine use for distinguishing benign and malignant breast tumors. But its diagnosis is operator dependent. In previous researches texture analysis for solid breast mass classification is used. In those works texture features of the tumor are used, but sonologists notice to the features of the surrounding area of the tumors for their diagnosis. In this research as well as the morphological features of the mass the features of the surrounding area of the mass are also considered. MLP neural network is used for classification. 36 breast sonography images are used that 18 of them proved to be benign and 18 of them proved to be malignant through biopsy. The features are used in different combinations and it is shown that using the texture features of behind the tumor area and the same depth near the tumor provide meaningful result and also compensate the different adjustments of the systems.

First, in the learning phase, training samples of intact and defected blocks of the texture image are collected and transformed to the curvelet domain. Next, for each block a feature vector based on curvelet sub-bands is extracted and using a proposed method some important and effective features are determined for the desired texture. Then, a proper threshold for detecting defected from intact blocks is determined. In the performance phase, a vector containing the important features from each block of the texture is extracted and then the block by is classified. The results of simulation show that the proposed system is superior to the mean shift method in detecting defected texture blocks, and is less sensitive to the type of texture. Manuscript profile

The images of steel surfaces are generally textural images. There are different texture analysis methods to extract features from these images. In those methods using multi-scale/multi-directional analysis, Gabor filters are used for feature extraction. In this paper, we extract texture features using the optimum Gabor filter bank. This filter bank is designed in a way that diverse filtering frequency and orientation will allow it to extract considerable amounts of texture information from the input images. We also introduce a new method called Gabor composition for segmentation and defect detection of steel surfaces. In this method, using two different algorithms, the input image is decomposed into detail images using an appropriate Gabor filter bank and then selected detail images are re composed. The created feature map illustrates the defective areas well. By calculating data distribution of detail images and comparing them, the second method of Gabor composition can accomplish segmentation without needing the normal images and the number of detail images to re-compose. Furthermore, we did different tests towards optimizing of segmentation by means of classifiers. Using a K-means classifier and adding gray levels to the extracted features, complete the segmentation procedure. The experimental results show that the Gabor composition method in most of the tests has got better defect detection performance than the ordinary K-means classifier and the standard wavelet method; also the Second method of Gabor composition has got the best performance over all.

Object boundaries detection is one of the interesting subjects in computer and image processing. Active contour models are one of the popular methods in object detection and segmentation. This paper presents a new method for segmentation of texture object by means of parametric active contour. In this proposed method, by adding a balloon energy to energy function of the parametric active contour model, the detection and segmentation of textured object against textured background would be achieved. In this method, texture feature of contour and object points are calculated by contourlet transform. Then by comparing these features with texture feature of target object, which are available as prior information, movement direction of balloon is defined, whereupon contour curves are expanded or contracted in order to adapt to the target boundaries. Experimental results demonstrate that the active contour based on contourlet (Contourlet-ACM) has higher segmentation accuracy than the active contour based on moment (Moment-ACM) and active contour based on DWHT (DWHT-ACM).

In this paper, a novel low-level image feature extraction and indexing scheme based on structure-texture image decomposition is presented. The main idea of this work is to decompose database images to structure and texture sub-images to decrease the destructive effects of simultaneous existence of structure and texture information in the image in indexing phase. It is also shown that precision in a typical content-based image retrieval system can considerably increase by combining the feature vectors extracted from structure and texture sub-images. An image database containing 10000 images of 82 different semantic groups is used to evaluate the proposed method. The results confirm the effectiveness of this method. Manuscript profile

Texture classification is one of the main steps in image processing and computer vision applications. Feature extraction is the first step of texture classification process which plays a main role. Many approaches have proposed to classify textures since now. Among them, Local Binary Patterns and Modified Local Binary Patterns, because of simplicity and classification accuracy, have emerged as one of the most popular ones. The Local Binary Patterns have simple implementation, but with increase in the radius of neighborhood, computational complexity will be increased. Modified Local Binary Patterns assigns various labels to uniform textures and a unique label to all non-uniform ones. In this respect, the modified local binary pattern can't classify non uniform textures as well as uniform ones. In this paper a new version of Local Binary Pattern is proposed that has less computational complexity than Local Binary Patterns and more classification accuracy than Modified version. The proposed approach classifies non uniform textures as well as uniform ones. Also with change in the length of central gray level intervals, locality and globally of the features can be controlled. Classification accuracy on two standard datasets, Brodatz and Outex, indicates the efficiency of the proposed approach. Manuscript profile

Texture classification is one of the important branches of image processing. The main point of texture classification is feature extraction. Local Binary Pattern (LBP) is one of the important methods that are used for texture feature extraction. This method is widely used because it has simple implementation and extracts high discriminative features from textures. Most of previous LBP methods used uniform patterns and only one feature is extracted from non-uniform patterns. In this paper, by extending non-uniform patterns a new mapping technique is proposed that extracts more discriminative features from non-uniform patterns. So in spite of almost all of the previous LBP methods, the proposed method extracts more discriminative features from non-uniform patterns and increases the classification accuracy of textures. The proposed method has all of the positive points of previous LBP variants. It is a rotation invariant and illumination invariant method and increase the classification accuracy. The implementation of proposed mapping on Outex dataset shows that proposed method can improve the accuracy of classifications significantly. Manuscript profile

Dilapidated urban structures, regardless of their different species, are the product of some negligence of urban management, which over time has become an area of the city that lacks the necessary physical stability and strength, does not provide adequate access to their homes and lacks Severe service suffer. For this reason, due to the low quality of life in some parts of them, the housing of deprived and rural immigrants and some non-Iranians have become and finally have become unsafe places with many social anomalies at the lowest level of environmental quality. What has faced the problem of intervention, improvement and renovation of worn-out structures in our country is the lack of a clear strategy based on the identification of worn-out tissue species and the serious determination of urban management to renovate and improve them. In many areas, contextual improvement and micro-partnership with the people living in it, offers a very desirable and sustainable method that can be done over a short period of time. Qom city is one of the cities that is clearly facing the problem of erosion due to having about 1074 hectares of historical and dilapidated texture and the residential texture around Qom Grand Mosque, due to its special location and being located in the central and historical area of Qom city and its erosion. He faces certain problems. The findings show that a survey of residents' satisfaction shows that 32% completely agree with the demolition and renovation of the building, 23% agree, 20% somewhat agree, and there are those who are interested in this area and intend to continue living in the area. 15% of the residents of the area agree with the repair and reconstruction of the area but oppose the demolition and renovation. 10% are also dissatisfied with any changes in the buildings and structures of the area.

Human settlement was the beginning of his urbanization. To the extent that this growth of urbanization has created many social, economic and political issues in recent decades. One of these problems is the dilapidated urban structures, whose renovation and improvement has attracted the attention of urban planners and managers in recent decades. In such a situation, it is necessary to revive these tissues by using appropriate policies such as reconstruction, rehabilitation, renovation, improvement, redevelopment and finally regeneration. Renovation and improvement does not happen once and for all, but is a continuous thing. This is not instantaneous and fast, but a sensitive and complex process that requires the design of short-term, medium-term and long-term targeted programs and to achieve Successful organization and revitalization requires a detailed understanding of the old context and the entire city system and regional system. Therefore, in the present research, an attempt has been made to address the issue of improvement in the dilapidated fabric of Karaj city through the formulation of strategies. The results show that the factors of creating suitable institutional and legal frameworks for the purpose of integrated urban management, empowerment and capacity building in the municipalities and Islamic councils of the city are considered to be the most effective strategies for the regeneration of the worn-out fabric of Karaj city. Future. Also, the effective factors on renovation policies are: "simplifying the processes and steps of action for the renovation of buildings in run-down neighborhoods" and "supporting the establishment of neighborhood renovation service offices". In addition, "the use of non-governmental organizations in worn-out areas and neighborhoods" were identified as influencing factors on the issue of renovation. Manuscript profile
