In this paper, an efficient method for human facial expression recognition is presented based on LBP descriptor. Firstly, the face normalization is employed in order to improve the efficiencies of extracting facial features. Then, the feature blocks which mainly contain the eyes and mouth were obtained, and each feature block image was divided into several overlapping sub-regions equally to extract LBP histograms. After that, the PCA method is used to learn the structure of the expression in… CONTINUE READING
