关 键 词：expression recognition PCA image reconstruction D-value summation similarity
摘 要：The article proposed a new way of facial expression recognition by reconstructing the PCA *** the training set into 7 parts by expression,and get the Orthonormal Basis of each subset expression by PCA *** make projection with the original image on each of the Orthonormal Basis,rebuilt the projection coordinate and recognize the expression by the combination of D-value summation and similarity ***,we get the final result by comparing the similarity between the original and reconstruction image.
