基于测地线环的三维人脸快速识别算法

Fast 3D face recognition algorithm based on geodesic stripes

针对基于测地线环的三维人脸识别算法计算复杂度过大的问题,提出一种快速识别算法。提取等距测地线环的刚性部分作为特征,利用新3DWWs度量测地线环间的空间位置关系;以图模型构造不相似度作为匹配指标,采用一种由粗到精的匹配策略对三维人脸进行匹配,从而得到识别结果。在浙大人脸库FaceWarehouse上的实验结果表明,相较于传统测地线环算法,该算法在识别速度方面提高了15倍,且识别率达97%,相较于现有的其他算法识别率较高。

A fast recognition algorithm is proposed to solve the problem of high complexity of 3 Dface recognition algorithm based on geodesic stripes.We extract rigid parts of the equidistant geodesic stripes as features,and exploit new 3 DWWs to measure the spatial position of geodesic stripes.We use the graph model to form dissimilarity as matching targets,and propose a matching strategy from coarse to fine to match 3 Dfaces,and then obtain the recognition results.Experimental results on FaceWarehouse show that our algorithm improves the recognition speed by15 times compared with the traditional algorithm based on geodesic stripes,and the recognition rate is up to 97%,which is higher than some existing algorithms.
