Fractal image compression can be obtained by dividing the original grey level image into unoverlapped blocks depending on a threshold value and the well known techniques of Quadtree decomposition. By using threshold value of 0.2 and Huffman coding for encoding and decoding of the image these techniques have been applied for the compression of satellite imageries. The compression ratio (CR) and ...

the objective of this article is to present the established components with regard to the visual quality and legibility of isfahan city according to lynch’s theory. data was gathered in isfahan mainly by way of observation and interviews. additional information was obtained from historical data and urban documents. in the opinion of the citizens, the zayandehrood river, as a natural urban compo...

High-resolution satellite imagery has been regarded as one of important datasets to analyze urban environment composed of complex features. In this study, texture-based image analysis was applied to characterize urban features for regional planning, and firstly new implementation with user interface and main algorithms for this purpose was performed for texture image generation and wavelet imag...

Accurately detecting urban expansion with remote sensing techniques is a challenge due to the complexity of urban landscapes. This paper explored methods for detecting urban expansion with multitemporal QuickBird images in Lucas do Rio Verde, Mato Grosso, Brazil. Different techniques, including image differencing, principal component analysis (PCA), and comparison of classified impervious surfa...

Automatic road network extraction based on high resolution satellite image for urban planning holds great potential for significant reduction of database development/updating cost and turnaround time. Satellite remote sensing has been recognized worldwide as an effective technology for the monitoring and mapping the urban development. Two approaches for road network extraction for an urban regi...

urban space can be the most successful public arena in this century if employ the potentialsfor collective cooperation in creative ways in order to provide further services. the theory of creative city tries tostrengthen the qualities which enhance the image of a city for the citizens and create a dynamic city in terms of cultureand intercultural learning. therefore, the existence of generator,...

urban landscapes form the main parts of the city. one of these spaces is urban streets, in whichsocial interactions and urban vitality reach its maximum quality and quantity. one of the principles and properties ofurban landscape design is its intelligibility. a viewer who takes a look at an intelligible city and knows it can attract newemotional manifestations of city without damaging its orig...

the logistic regression (lr) method, as an empirical estimation method, was used to model urban growth in gorgan city between the years 1987-2001. three groups of variables including social-economic, land use and biophysical variables were used. similarity among variables is probable. to remove the correlated variables, covariance was calculated and distance to administrative, sporting centers ...

With the rapid development of cities, the way that people commute has changed greatly, meanwhile, people turn to require more on physical and psychological aspects in the contemporary world. However, the current urban road landscape ignores these changes, for example, those road landscape elements are boring, confusing, fragmented and lack of integrity and hierarchy. Under such current situatio...
