Human skin color distribution is relatively compact in a color space. That skin pixels in each frame are closed together as a ??dot cloud?? is hypothesized, the shape evolution of ??dot cloud?? in the color space from frame to frame is parameterized as translation, scaling and rotation. The linear combination of forecasts, which is consisted of 2-order Markov predictor and Wiener one step predictor,...
