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。

This algebraic notation of the image allows the entire image to be recreated at any time.
图像的代数标记法可以在任何时间重新创建整个图像。
This algebraic notation of the image allows the entire image, or just a portion of the image, to be recreated at any time by evaluating the algebraic description over the range of interest.
由于用几何方法表示图像，所以可以在任何时候在一定范围内计算几何描述，从而重新创建整个图像（或一部分图像）。
Firstly, the image is projected on to the orthogonal basis of SVDQ, then the projection coefficient vector is used as algebraic feature of image and applied to recognition.
该方法将图像投影到SVDQ的各个正交基上，得到投影系数向量。将此向量作为图像的代数特征并用于彩色图像识别中。
