The recognition of facial expressions considering the difference between individualities
Hideyuki Ebine, Osamu Nakamura · IEEJ Transactions on Electronics Information and Systems · 1999
In this paper, an algorithm to recognize facial expressions considering the size difference between the individual faces is proposed. The size differences between the individual faces becomes a problem for extracting effective features. On the contrary, in the recognition of facial expressions, the differences between the individuals must be considered and the judgments should be achieved considering each specific area. From these points of view, we propose a facial expression recognition system considering the size differences between the individual faces. Computer simulation using 59 expressive facial images shows more than 86.7% accuracy. From the experimental results, the prospects of using this method are very encouraging.
