摘　　要：本文提出了一种新的自动图象边缘检测方法。该方法使用新的隶属函数将图象转化为等效的图象模糊特征平面 ,在此基础上进行模糊增强 ,然后再转换为空域图象 ,最后进行边缘提取。模糊增强提高了低灰度区域和高灰度区域之间的对比度 ,从而使提取的边缘效果更好。In this paper,an automatic algorithm of edge detection is proposed.This algorithm is performed by extracting the fuzzy property plane from the spatial domain with a new membership function,executing the fuzzy enhancement,obtaining the modified spatial domain and extracting the edges of the modified image.In order to get much better quality of the edge detection,the contrast among the regions is increased using the fuzzy enhancement.This algorithm is also extended to the edge detection of the multi threshold image.
