The Edge Detection of Gray Image Based on Wavelet Transform and SUSAN Operator

In this paper,a edge detection algorithm of gray image is presented based on wavelet transform and SUSAN operator.Firstly,the image which will be detected will be decomposed with multi-scale wavelet,and the high frequency part are obtained.Secondly,through dealing with the high frequency detail information of image,we will get the image border information.The experiment result can certificate that our method is good and have the very strong pragmatism.
