基于小波变换和SUSAN算子的灰度图像边缘检测算法

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

根据小波变换的多分辨率特性和SUSAN算子良好的抗噪和检测能力提出了一种灰度图像的边缘检测算法。首先对待检测的灰度图像进行小波多尺度分解,得到高低频信息;然后对高频细节信息进行SUSAN算子的处理得到图像的边缘信息。实验结果证明,该方法效果良好,具有很强的实用性。

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.
