摘　　要：图像边缘检测是一种非常经典的基于计算机视觉技术的图像处理技术,主要是根据图像的某种特定信息,把目标的边缘与周围的区分开来。回顾了几种传统的边缘检测方法,并分析它们的优缺点,详细阐述了Canny算子的检测原理和实验方法。实验结果表明Canny算子是最优的边缘检测算子,能够较稳定地对目标图像进行边缘信息提取,得到较好的检测效果。Image edge detection is a very classical image processing technology based on computer vision technology, which distinguishes target’s edge from its surrounding mainly according to some specific information. Several traditional methods of edge detection are reviewed in this paper,and their merits and demerits are analyzed. The detection principle and experimental methods of Canny operator are elaborated. Experimental results show that the Canny operator is the best edge detection operator,can extract the target image edge information stably and get better detection results.
