Abstract
An efficient video coding algorithm for coding the upper half of a human body is proposed. In the coding system, the facial area, which is a moving object in the image sequence, is extracted from both the sending and receiving sides without any control information. The candidate areas of the person are segmented using color information and the moving areas. The color information, which represents skin color, is extracted with a modified HSV color system. The moving areas are estimated using motion parameters of objects, which are utilized for constructing previous frames. The face is then extracted by merging the candidate areas based on hue elements of the modified HSV color system. The standard “Claire” and “Miss America” videos are used for the computer simulation, and facial areas are accurately extracted in all frames.
