Adaptive coding based on a new slice type in surveillance systems

Abstract

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].
