基于融合特征提取与LLE方法的表情识别
Expression Recognition Based on Fusion Features Extraction and LLE Method
摘要
Abstract
Feature extraction is a basis, a vital step and a major issue in facial expression recognition. To ensure that the extracted features can be more comprehensive characterization of a certain kind of expression, we present a feature extraction method based on fused geometry and local texture features. Geometric features are obtained from the feature points marked by AAM ( Active Appearance Model) algorithm, texture feature extraction is based on LBP ( Local Binary Pattern) algorithm, the dimension of fusion expression features is reduced by LLE ( Locally Linear Embedding ) algorithm. Finally, a multi-class SVM ( Support Vector Machine) is used for facial expression classification. Our method is deployed on the JAFFE and Yale data sets, the results show a recognition accuracy of 98. 57% and 91. 67% respectively, which prove the effectiveness of our proposed method.关键词
