Position tracking of the mouth using image processing.
In this paper, an image processing method using CMOS camera was applied to an assistive system to care for bedridden people. It was experimentally demonstrated that 2-dimensional position tracking of the experimental subject's mouth was performed using image processing. Furthermore, 3-dimensional position tracking of the subject's mouth was measured using stereo matching measurement. From the experimental results, it was clear that the 2-dimensional position of his mouth was correctly tracked 90 % in all frames, and that the 3-dimensional position tracking of his mouth was effectively measured.
