In this paper, we propose a method of extracting and tracking regions of human face and hands appeared on sequential images considering fusion of color information and tracking region. Conventionally, it has been hard to extract the skin regions of human in the case when a background reflects skin color objects like corrugated cardboards, or including moving picture such as TV screen. Coping with such kind of difficult situation to extract skin regions, we firstly obtain three kinds of information based on background color, skin color and its tracking skin regions, then apply Dempster-Shafer's combination rule to the three kinds of information. This approach using the fused information becomes a robust extraction method, because other information can extract the regions even if one of the information lacks. The effectiveness of our approach is examined by the experiments.
