Abstract :
In this paper, we propose an algorithm using only two commodity webcams without calibration to detect distance between user and display by face detection. According to the experimental result, the correlation coefficient of distance and the reciprocal of disparity is up to 0.9984. Our proposed algorithm can provide user´s depth information with high accuracy from calibration free stereo capture image pair for the application, such as interactive 3DTV or user-aware auto-stereoscopic display.
