Abstract

In this paper, the importance of edge extracting in image processing and the analysis of the superiorities in edge extracting by using wavelet transform are given, these superiorities are described as: time and frequency domains, multiresolution, pure mathematical method. Based on much reference, some wavelet functions for edge extracting are made, the effect and methods for edge extracting by using these wavelet functions are also made, and the computer simulation results for Linna image by using these wavelet functions and methods are given, from these simulation results we can get that the derivative of Gauss function is often used as wavelet function and has good effect in image edge extracting, at last, we give the computer simulation results for edge extracting by using the derivative of Gauss function, we process a building under different clarities.
