Abstract

The computer-based recognition of facial expressions has been an active area of research in the literature for a long time. The most expressive way humans display emotions is through facial expressions. In this paper we present a method to analyze facial expression from images by applying Gabor wavelet filter banks on face images. To reduce the computational complexity a set of selected Gabor filters are used. The query image is compared with the images in the database by a phase Sensitivity Similarity function. A Support Vector Machine is used to classify different kinds of facial expressions belonging to the face image. This method exhibits a better performance ratio.
