| Outline of Final Research Achievements |
A method for recognizing a micro expression which is a small motion appearing on a face by using a high density and high frame-rate 3D reconstruction method are developed. In order to verify the set of methods to identify the site of micro expression and its accuracy, as a simple recognition problem, vocalizing unknown words was assigned to be further analyzed mechanically. As a result, by using highly accurate data of the facial movement, we were able to identify feature parts that matches with the human mental state, and able to estimate at about 75% accuracy. On the other hand, if the accuracy of the face shape measurement was decreased by few 10mm and lower the frame rate to 20fps, recognition of the micro expression became troublesome.
