A facial expression recognition strategy based on template matching

To solve the problems of lean, occlusion, and unbalance exposure, a new strategy of facial expression recognition based on template matching is proposed in the paper. The strategy firstly obtains the characteristics of half-facial expressions by using Gabor wavelet, and then calculates the picture's Euclidean distance with the standard library; at last, classify expressions by using the method of K nearest neighbor. Experiments show that the...
