Recognition of Facial Expressions Using Neural Networks

In this paper, we develop a novel recognition system of human face expressions by using neural networks. An essential core of the recognition system is a new categorization method of the facial image data for the neural network learning. The categorization is carried out not based on self-assessment of the person who shows the facial expressions, but on more objective judgements by the 3rd persons. Simulation results show that the proposed system can recognize the facial expressions more easily and accurately compared with conventional method
