| Abstract: | Edge information in remote sensing image provides a rich content for image understanding.An algorithm to calculate the fractal dimension of a single pixel by using the model of DFBR(Discrete Fractal Brown Random field)is designed.This algorithm is programmed by Matlab.Map the image gray level space to the fractal dimension of space,and then transform and edge detection in the latter one.Spatial distribution of surface features and the differences of image texture structure and edge features,make the selecte... |
