Abstract :
The fractal parameters are extracted from 5 scenes multi-temporal fine mode Radarsat images using the method based on superficial area-volume relation. The results show that the fractal dimension reveals the surface roughness information of the image plane and the constant value exhibits the edge information clearly. Putting the fractal parameters such as texture parameters into a neural net classifier for landuse investigation in Zhaoqing test site, it indicates that the average accuracy of classification of 11 targets in this area is improved from 86.66% to 96.19%
