| 摘 要： | 针对如何提高人脸图像识别率问题,提出了利用粒子群优化(PSO)的人脸特征提取识别算法.采用小波变换和张量主成分分析(PCA)方法对人脸图像进行特征提取,利用PSO对提取的特征进行加权处理,根据特征的每一维元素的聚类正确率进行优化选择,从而达到对人脸提取关键性特征的目的.实验结果表明,所提算法能减小光照、表情和姿态变化的影响,在英国曼彻斯特科技大学人脸数据库上的识别率比张量PCA方法提高了12.75%.

| Abstract: | A face recognition algorithm with optimal features extraction based on particle swarm optimization (PSO) is proposed to enhance the recognition rate. Features of each face image are extracted by using the wavelet transformation and the tensor principal component analysis (PCA) algorithm. Weights of the features' elements are then determined using PSO according to the right clustering rate of each element,so that the object to extract the key features of the faces can be realized. Experimental results on the... |
