A facial expression recognition algorithm named PCA (Principal Component Analysis) reconstruction to the still image containing facial expression information is proposed. The general idea of the algorithm is classifying the training sets of facial expression into different subsets by facial expression. Then apply the PCA algorithm into the subsets to get the corresponding orthogonal basis. Test images project on the orthogonal basis of different expression subsets, and reconstruct based on the… CONTINUE READING
