A Wavelet Based Edge Detection Algorithm
Edge is in the place where image gray scale changes severely, it contains abundant image information. Image edge detection is a hot and difficult research field. Compare and analyze several classic edge detection method, aim at the advantages and disadvantages, respectively, propose a multi-scale edge detection algorithm based on the wavelet. The simulation shows the algorithm obtains an ideal effect in edge location and noise suppression.
