中文说明：应用背景在图像处理中，我们有时候要获取图像边缘的信息，比如散焦模糊圆半径的检测，人物图像边缘的检测等，这些都要用到边缘检测，本文给出了八种边缘检测算子，并能取得不同的图像效果。关键技术 本文用两个常用的图片cinema、lena，演示了八种边缘检测算子，包括canny算子，kirsch算子，Laplacian算子，log算子，prewitt算子，robert算子，robinson算子，sobel算子，每种方法都有不同的优越性。
English Description：
Application backgroundIn image processing, we can get the information of image edge, such as the detection of the edge of the image, the edge detection, the edge detection, and the eight kinds of edge detection operator, and can obtain different image effects.Key TechnologyIn this paper, two kinds of edge detection operators, including canny, Kirsch,, Laplacian, log, Prewitt,, Robert,, Sobel,, Robinson, Lena, cinema, and, each method has different advantages.
