英语翻译其余的内容构成如下.在第2节,我们描述理论和算法的边缘侦测.对理论的离散广义分布（DSC）进行简要回顾.两个新类

The rest of the content as follows.In the second quarter,we describe the edge detection algorithm theory and.The theory of discrete generalized distributed (DSC) are briefly reviewed.Two new category of edge detector is used in multi-scale characteristic extraction under normal and noisy environment.Hot edge detector (DSCED) is to build fine multi-scaling edge detector.In addition,DSC antinoise edge detector (DSCANED) design into thick multi-scaling edge detector.This algorithm is applied in the third quarter.The utility illustrates some real images.Both the image and noisy noise in image processing.Performance of the proposed approach is objective measure of using test.The conclusion is obtained in the fourth quarter.
