Abstract

Abstract: A novel approach to facial expression recognition based on the combination of Local Binary Pattern（LBP） and Support Vector Machine（SVM） is proposed.First，the algorithm processes facial expression images with LBP operator and then facial expression features are formed by statistics of image’s LBPs.Then Linear Discrimination Analysis（LDA） method is used for feature dimension reduction and SVM for classification.Finally，the algorithm is implemented with Matlab and experimented in Japanese Female Facial Expression database（JAFFE database）.A recognition rate of 70.95% is obtained and shows the effectiveness of the proposed algorithm.

Key words: facial expression recognition, Local Binary Pattern（LBP）, Linear Discrimination Analysis（LDA）, Support Vector Machine（SVM）

摘要： 提出了一种基于局部二元模式（Local Binary Pattern，LBP）与支持向量机（SVM）相结合的面部表情识别方法。使用LBP算子对图像进行处理，对图像的模式进行统计形成面部表情特征；使用线性判别分析对表情特征进行降维处理；采用支持向量机对面部表情进行分类。用Matlab实现了上述方法，并在日本女性人脸表情（JAFFE）数据库上测试，取得了70.95%的识别率。
