| Abstract(in English) | The purpose of this study is to estimate three-dimensional motions of the sign language with a single camera. In the system, a three-dimensional human model with three-dimensional polyhedrons with nine degrees of freedom was prepared, and two-dimensional image sequences with a CCD camera were applied. Moreover, optical flows in three frames before current time were used for the motion estimation, so that the system can be robust to self-occlusions by performer's own face and body. In the experiment, standstill, straight, circular, arc motions and their combinations were adopted for the estimation. As the results, the system realized the gesture estimation and tracking with high accuracy. In the experiment of reproducing three-dimensional motions with computer graphics, gesture reproductions were performed within 0.34ms per a frame without any specific computer hardwares. These results showed that the system is effective for three-dimensional motion estimation for sign language with a single CCD camera. |
