Robust Computer Vision for Computer Mediated Compunication

摘要

In Computer Mediated Communication, static video cameras provide a restricted field of view of remote sites. he concept of virtual window has been introduced to alleviate this problem. Although this technique is interactionally attractive, early implementations have proved unstaisfactory because of lack of robustness. In this paper we demonstrate that robustness and accuracy can be increased by combining multiple cmputer vision techniuqes such as eye blink detection, skin color histogram and corss correlation, that adapt to a variety of operating conditions.
