A human face model based upon disassembly and assembly of constituents through analysis of human facial images; feature vectors representing human facial expressions are extracted by energy optimization of template matching;an expression classification tree is established through analysis of facial expression images,shapes and relative positions of components,and identification of expressions is achieved by classification of patterns;and a number of improvements has been incorporated to make the system an on-line real-time system.
