摘要
边缘检测是人脸表情识别的重要环节之一，该文通过分析常用边缘检测算法，如R．oherts算子、Sobel算子、Prewitt算子、Canny算子、Laplacian算子、Log算子，实现了一套运用nsharp滤波算子、Canny边缘检测算子综合处理人脸表情识别的边缘检测方案，并运用日本JAFFE表情库，通过MATLAB仿真实验验证了这种方法的有效性。
Edge detection is one of most essential basic technology in Image Processing area.This paper analyz some commonly used edge detection algorithms,such as Roherts operator, Sobel operator, Prewitt operator, Canny operator, Laplacian operator and Log operator. It achieve a new proposal to detect edge in facial expression recognition joining nsharp filtering operator and Canny edge detection.The MATLAB simulation experiment prove the effectiveness on Japanese JAFFE expression library.
