Human Body Tracking for Human Computer Intelligent Interaction

For interactive mixed reality applications, a novel human body detection and tracking method is presented. The method automatically detects moving body regions and tracks them continuously until they disappear from the camera field of view. Two main cues, skin color and motion, are used to track visual attentions. The method can be used for applications of the attention based human-computer interfaces where attentions are mostly focused on human body parts. In our experiments, the method provided correct results whenever at least a patch of moving body parts was disclosed with skin color.
