A 5-band Temporal Lifting Scheme for Video Surveillance

Abstract

Three-dimensional (3D) wavelet coding schemes have been demonstrated to be efficient techniques for video compression applications. The scalability property of such schemes is one of the most important issues for video surveillance systems. In this paper we introduce a new lifting-based method of temporal decomposition which provides a scalability factor of 5 in a motion-compensated subband video coding scheme. Depending on the sequence characteristics, motion model etc., this structure can provide high coding performance. Also, it gives a better coding efficiency for the temporal approximation subbands, thus leading to an improved temporal scalability. It addresses video surveillance applications, where the motion is very low in most cases.
