| 摘 要： | 在2DPCA的基础上提出一种随机采样的2DPCA人脸识别方法--RRS-2DPCA.同传统通过对特征或投影向量进行采样的方法不同的是,RRS-2DPCA(Row Random Sampling 2DPCA)将随机采样建立于图像的行向量集中,然后在行向量子集中执行2DPCA.在ORL、Yale和AR人脸数据集上进行实验,结果表明RRS-2DPCA不仅具很好的识别性能和运算效率,而且对参数具有很大的稳定性.另外针对2DPCA和RRS-2DPCA对光线、遮挡等不鲁棒问题,进一步提出了局部区域随机采样的2DPCA方法LRRS-2DPCA(Local Row Random Sampling 2DPCA),将RRS-2DPCA执行在人脸图像的局部区域中.实验结果表明LRRS-2DPCA不仅具有较好的鲁棒性更大大的提高了RRS-2DPCA的识别性能.

| Abstract: | Proposed a 2DPCA method based on random sampling,termed as Row Random Sampling 2DPCA(RRS-2DPCA),for face recognition.Different from those traditional face recognition methods which sampling from feature or feature vector,RRS-2DPCA constructs random sampling on row vector sets and then performs 2DPCA on those row vector sets.The experimental results on ORL,Yale and AR face databases show that RRS-2DPCA not only obtains very good recogntion accuracy and computational efficiency,but also is stable to the numbe... |
