A method for image edge detection based on image fusion is presented. Because the traditional wavelet analysis is unable to control the noisy well and the edge is not consistent to direction properties some improvements have been made and a new kind of wavelet transform has been proposed. It detects the edge of original image by the means of new wavelet transform and Canny operator respectively

then does image fusion of the two results that produced by those two detecting method. It is shown that the propos...
