Abstract: An enhanced loitering detection scheme is proposed that uses a look-ing-around feature along with the moving pattern features which can be extracted from partial trajectories, to differentiate loitering of a per-son from normal walking in surveillance videos. The looking-around feature is extracted based on the change amount of the skin color pix-els in the person’s head area within the continuous video frames. With the looking-around feature, the enhanced scheme can detect loitering behaviors more accurately with 92% accuracy than the previous loiter-ing detection scheme of 88%, especially for loitering of a person who is looking around frequently to check surrounding circumstances as the person moves forwards.
