Abstract
This article analyses the Gauss noise characteristics of common image , studies the edge detection method based on digital image which contains a strong Gauss noise. It analyses directional correlation feature edges and continuity characteristics , design the image feature vector, detects similarity of image feature vector related, extract image edge detection method of anti-noise. The simulation results show that, for images with a strong Gauss noise, the proposed method can effectively suppress the noise, and can extract accurate and clear edge. This method can well overcome the noise problem of common operators in noise image , but also has a simple algorithm with less calculation.关键词
