一种基于二次直方图距离的人脸识别方法
Face recognition method based on quadratic histogram distance
摘要
Abstract
A face recognition method under no constraint conditions is proposed. Facial images are transferred to a set of block feature vectors using Prewitte operator, in which more local information is considered. A modified Quadratic Histo-gram Distance(QHD)is applied to measure the similarity of these feature vectors, the weight matrix of QHD is adjusted to improve recognition accuracy. Face recognition is implemented based on combination of the modified measurement and feature descriptor. Experimental results show the algorithm has better performance than original methods to some extent.关键词
