Arithmetic of traditional segmentation and extraction of region bases on extraction of shape of objects. Because of existence of a great deal of speckle noise and fuzzy information in SAR image, it is ditficult to realize the segmentation of region. In the light of special abilitj, of dimension of fractal in the aspect of expressing roughness of texture, region segmentation of SAR image based on dimension offractal gets an ideal result.
The research is based on data derived from fieldwork that is interpreted using fractal theory. The present study relied on multi-time satellite remote sensing data for the main sources of information. With the aide of image analysis techniques, desertification of Qira county and changes in the oasis-desert ecotone are analyzed.. In addition, the function of fractal theory in highly quantitative research of oasis-desert ecotones is discussed.. We suggest that the model derived from the present study should serve as a reference in decision-making concerning regional development and construction in order to simplify existing research processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
