一种改进的人脸边缘检测方法

人脸检测和识别技术在公共安全、图像检索、人机智能交互等方面有着巨大应用前景.在民事和经济领域,各类金融卡、信用卡的持卡人的身份验证,社会保险人的身份验证等具有重要的应用价值.边缘检测是人脸检测的关键技术之一,文中论述了一种全新的二次边缘提取算法以及图像的归一化处理.采用的算法既可以优化图像质量,又可以完成对图像的二值化处理和边缘提取.Matlab和Yale人脸库实验表明,该算法简单、快速,在一定程度上优于著名的Prewitt和Sobel算子.

An Improved Method of Edge Detection in Face Recognition

The face recognition may be applied in many fields such as identity recognition and public security documents management.The edge detection is a key technology of human face recognition.This paper is about a new method of edge detection and its new development,binalization and unification.We use the algorithm of the second brim abstraction with which we not only optimize the quality of the images but also finish the binalization.Experiments show that the algorithm is simple and fast.To a certain extent the result is better than the famous Prewitt operator and Sobel operator.
