Investigation on Detection Algorithm for Fuzzy Image Edge
摘要
Abstract
Since the image edge corresponds to the gray mutation and/or discontinuous position of image,the traditional differential edge detection is the image gradient algorithm based on certain forms.In comparison with a predetermined threshold,if the calculated edge gradient value exceeds the threshold value,the edge is taken as the current edge.The traditional algorithm can meet the requirement for the image edges with distinct variation of gray level.But for certain indistinct gray level variation,the detection effect is not satisfactory,even especially not be detected.Therefore,a fuzzy edge detection algorithm has been proposed where more edge features can be detected via enhancement of image edge contrast to improve the detection effect.In order to verify and validate the proposed algorithm,experimental contrast simulations have been conducted with traditional Sobel algorithm versus Log algorithm.The results show that compared with the traditional edge detection operators,the proposed fuzzy edge detection algorithm is more superior and effective.关键词
