Canny算法的改进

Improvement of Canny Algorithm

边缘检测是计算机视觉中重要的研究内容,Canny算法是其中较为典型的算法。文中分析了Canny算法,将其改进到彩色空间上实现,使得该算法可以直接用于处理二值、灰度和彩色图像,并且边缘数据量大为减少。实验结果表明,算法具有通用性,且提高了边缘检测速度。

In computer view, edge detection is a hot research area, in which Canny algorithm is a typical algorithm. This paper analyzes the calculating way of Canny and improves it into colorful space on the realization. The algorithm can be used to handle directly two value, gray-scale and colorful image. At the same time, the edge data quantity are reduced greatly. The experiment result indicates that the algorithm is universal and the detection speed has been raised.
