A color information and reproduction method for the Virtual Space Teleconference System is described. In this system, different perspectives of a human image corresponding to different viewpoints have to be synthesize from a single input human image. The shape, motion and color information of the input image is first analyzed, and then a synthesized image is generated to suit the required conditions. The proposed method is concerned with the color information analysis and synthesis part in that process. The input human image is segmented into perceptual color regions of similar class, where the color information is coded independently of shape. Then the colors of the images corresponding to different viewpoints can be reproduced as required.
