The paper discusses facial expression recognition based on image algebraic characters. First, eyes and mouth are segmented from the facial expression image and variant moments and singular value feature vectors of eyes and mouth are extracted.
探讨了图像代数特征在面部表情识别中的应用，首先对面部表情图像进行了分割，得到眼睛和嘴巴区域，然后分别对眼睛和嘴巴区域提取不变矩和奇异值特征向量，并进行Fisher线性判别分析，最后训练了支持向量机分类器。
