Image Edge Extraction Algorithm of Fuzzy Enhancement
In this paper,a novel image edge extraction algorithm based on fuzzy enhancement was proposed by analyzing the deficiencies of Pal fuzzy edge extraction algorithm(Pal algorithm).By quoting fuzzy entropy,the selection of the threshold value in different levels was beneficial to a certain extent,defining a new membership function and a new fuzzy enhancement function combined with smooth filter of image edge extraction.The new algorithm could enhance image edges of different levels at the same time.In addition,the new algorithm simplified the complex transformation calculation.We use the novel algorithm to extract image edges,we can get a better result than that of the traditional Pal image edge extraction algorithm.
