Abstract :
A combined method for edge detection of SAR images is put forward in this paper. This method is composed of the wavelet transform, fuzzy median filter, adaptive thresholding and differential gradient operator. In using the fuzzy median filter, this paper gives a new method for adaptively selecting the factors of the fuzzy median filter. The experimental results show the effectiveness and stability of this method
