| 摘 要： | 提出一种二维Fisher线性判别分析(2DFLD)与局部保持投影(LPP)相结合的人脸和表情识别方法.首先，将训练集图像用2DFLD投影，使其按身份分离.然后，用LPP进行二次投影提取出它的表情流形.最后，给出概率度量，得到待测图像属于各类身份和表情的概率，从而识别出它的人脸和表情的类别.在CMU-AMP和JAFFE人脸库上的实验表明，该方法简便有效、识别效果好. |

| Abstract: | A face and expression recognition method by combing 2DFLD with LPP is proposed. Firstly, each facial image in training set is mapped by using 2DFLD according to its identity. Then, expression manifolds of training set are obtained by LPP. Finally, each identity and expression probability of test image is computed according to the given probability metric, and face and expression recognition of the test image is thus accomplished. The experimental results on CMU-AMP and JAFFE face database show the effectiveness of the proposed method. |
