Adaptive coding based on a new slice type in surveillance systems

In surveillance systems, low bit rate video coding is necessary to reduce the storage and bandwidth consumption, especially for high definition video coding. In [1], we proposed an adaptive coding method to code the active regions with traditional slices and background with the proposed S slice respectively. The S slice contains less syntax elements than the conventional P slice. This paper further analyzes the influence factors to the S slice coding. Moreover, a control module is proposed to enable the S slice coding and to find the best partition pattern between active regions and background that could get the most bit reduction [3], [4].
