Abstract Recognition of Facial Expression Based on SURF Takayuki Yoshimoto An expression plays a very big part in the human communication. It is said that the expression occupies about 55% of the whole dialog. And the expression is an element indispensable in order to perform a smooth dialog. If a computer becomes able to guess feelings from an expression, realization of high human interface understanding a human thought. Therefore, using SURF, I performed the recognition of facial expression experiment of 4 expressions (deadpan, smile, surprise, anger) and SURF characteristic quantity was effective for recognition of facial expression or, in this study, examined it. The result of deadpans 84%, smile 96%, surprise 28% and anger 32% have been obtained. Because it became a high recognition result about a deadpan, the smile, it is found that this technique is effective recognition to facial expression. key words SURF, Recognition of Facial Expression ii
