Expert system based on human facial expression image recognition

The present invention relates to a facial expression based on the image recognition method of the expert system, the method proceeds inference facial expression recognition of image preprocessing by establishing the expert system based on the conventional face image processing method, and a computer program functions on the the method comprises the following steps: 1) capture the video image, to obtain user information in the video, and then through image processing, the image feature extraction, authentication, acquires face image characteristic parameters of the user determine expression of the user database, establish recognizes human expert system of facial expression; 2) on the captured image from the video image processing and image feature extraction, feature parameters obtained to maximize the expression level of the user, the user characteristic parameter and the expression database in step 1) is determined in the training samples the expression parameters for comparison, through the expert system reasoning final output statistics facial expression recognition. Compared with the prior art, the present invention has the advantage of quick recognition speed.
