| 摘 要： | 本文提出了一种基于子模式的加权邻域极大边界准则的人脸识别算法.该方法首先在训练过程中对人脸图像进行子块划分,采用邻接点的类信息自适应地计算每块的权重以提高人脸在姿态、表情以及光照等变化下的鲁棒性.其次,对每块图像采用加权邻域极大边界准则进行特征提取,该准则充分利用了数据的类信息,选择数据的邻域点最优重构系数用在目标函数...

| Abstract: | A Subpattern-based Weighted Neighborhood Maximum Margin Criterion (SP-WNMMC) algorithm is proposed for face recognition. In order to enhance the robustness to facial pose, expression and illumination variations, SP-WNMMC method firstly operates on sub-patterns partitioned from an original whole face image. The contribution of each sub-pattern can be adaptively computed through the class information of neighborhood. Secondly, WNMMC is adopted in each sub-pattern to extract local features. WNMMC can preserve ... |
