Abstract
A novel approach for real-time skin segmentation in video
sequences is described. The approach enables reliable skin
segmentation despite wide variation in illumination during
tracking. An explicit second order Markov model is used
to predict evolution of the skin color (HSV) histogram over
time. Histograms are dynamically updated based on feed-
back from the current segmentation and based on predic-
tions of the Markov model. The evolution of the skin color
distribution at each frame is parameterized by translation,
scaling and rotation in color space. Consequent changes
in geometric parameterization of the distribution are prop-
agated by warping and re-sampling the histogram. The
