FACIAL EXPRESSION RECOGNITION BASED ON COMBINATION OF DIFFERENCE IMAGE AND GABOR WAVELET
摘要
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 difference images, and employ downsampling to reduce the dimensionality of the eigenvectors, and normalise the treated data, finally we use SVM to classify the facial expression. This combination method has been compared with the recognition method which only extracts the. Gabor feature from expression sub-region, the result indicates that the combination one has better recognition performance.关键词
