This paper presents a novel approach to face detection and tracking in video sequences. Probability distribution of the color for the human skin is used as major facial feature. A 2D histogram built from the color components of the image in YCrCb color space is used as representation of the model of the human skin. Facetracking involves the mean-shift algorithm. We propose a method for adaptation both of the tracking-window and of the color-distribution model in order to increase robustness to illumination changes of the environment. Minimizing of the number of iterations is achieved by using dynamic prediction with Kalman filter.
