Facial expression recognition based on data field

Abstract

Pattern recognition is a focused technique of computerized image analysis. One difficult problem of which is the uncertainty on the expressional face recognition. A new method on pattern recognition is proposed on the basis of data field. In the methodological framework of pattern recognition, the method is designed upon the data field and hierarchical modeling. This method is applied to recognize JAFFE, a famous expressional face database. The whole recognition rate may be about 94.3%. This result indicates that the method is suitable and effective.
