Based on the combination of wavelet transform and mathematical morphology, a novel approach for the edge detection is proposed in this paper. First, detect the image edge with multi-scale adaptive wavelet threshold method, and select proper structure element for dilation operation according to the types of mathematical morphology and process the(More)
