| 摘 要： | 提出一种结合差图像和Gabor小波变换的人脸特征提取方法,并使用支持向量机SVM(Support Vector Machines)进行人脸表情识别。对包含情感信息的静态灰度图像进行预处理,将眼睛和嘴巴等表情子区域从人脸中切割出来,求出其差图像,然后提取差图像的Gabor特征,使用下采样降维减少特征向量的维数并进行归一化,最后使用SVM进行分类。与只从表情子区域提取Ga-bor特征的识别方法进行了比较,结果显示识别效果更好。

| Abstract: | In this paper we introduce a facial expression features extraction algorithm which is the combination of difference image and Gabor wavelet transform,and use the support vector machine(SVM) to recognise facial expression.For a given static grey image containing facial expression information,pre-processing is executed first,the expression sub-regions including the eyes and the mouth respectively are cut from the face for obtaining their difference images,then we extract Gabor feature vectors of the differenc... |
