摘　　要：边缘检测是图像处理中很重要的组成部分,其效果直接影响到后面的图像分析。在此介绍Roberts算子、Prewitt算子、Sobel算子、LOG算子和Canny算子等经典边缘检测算子,对其性能和算法特点进行分析。运用Matlab进行算法的仿真,并对其检测结果进行分析和比较,得出Canny算子的边缘连接程度最佳,景物的细节表现得最明晰,轮廓边缘提取得很完备。Edge detection is a very important part in image processing, which impacts on image analysis to the back. The Roberts operator, Prewitt operator, Sobel operator, LOG operator and Canny operator are introduced the performance and characteristics are analysed. Using Matlab for algorithm simulation,and test results are analyzed and compared. Canny edge operator has best level of edge linking,clear details and very comprehensive outline of the edge extraction.
