This paper proposes a new approach to track a human head in 3-D voxel space. Information of both color and distance is obtained from multiple stereo cameras and integrated in 3-D voxel space. Formulating a likelihood function from voxel location and its color information can achieve stable tracking with particle filtering in 3-D voxel space.
