Abstract:
Traditional Sobel algorithm is deeply influenced by Gaussian noise, therefore, before boundary extraction, mean filter should be done. But the filtering process is always over-smooth images’ details of certain directions, so that images’ edges will not be extracted correctly. Aiming at this problem, this paper puts forward a detection algorithm based on edge-preserving characteristics, by matching edge mould of different directions to definite edge preserving directions. Instead of the mean filter process, this algorithm improves the performance of traditional algorithms, and provides the simulation results. The experiment results prove that this algorithm preserves more images’ edge information when canceling noise.
