All video sequences were taken simultaneously with static three non-calibrated cameras from different angle of view (horizontal view, angle view and top down view) with the frame rate of 25fps and were compressed with the huffyuv code in avi format. The original spatial resolution of the sequences was resized to 320*240. The duration of the sequences lasts from 5 seconds to 30 seconds due to different kind of actions.
