摘要
在计算机视觉应用中,低层模块中图像边缘提取检测通常是一个必要的过程。介绍了对计算机视觉中所应用的各种图像边缘提取技术;讨论了它们各自的优缺点及其适用范围;阐述了以小波变换为代表的多尺度方法;对具体选取哪种方法提出了自己的见解。
It is important to detect the image edge of the low tier model in the application of machine vision. This paper introduces all kinds of edge detection methods. Then, the merits and faults of edge detection methods are discussed. Next, the multi-scale method using the wavelet transform is described in detail. Finally the rule of choosing methods is presented.
