Abstract
MCTF (Motion Compensated Temporal Filtering) was firstly introduced in 3-D transform coding and has been used in several scalable coding proposals. The quality of the MCTF which plays an essential role in motion compensated 3-D subband/wavelet coding. The simplest implementation of MCTF in a lifting filter structure utilizes Haar filters, and longer filters such as 5/3 is also utilized extensively. In this paper, an improved db-2 based MCTF is proposed. The lowpass frames obtained by this db2-based MCTF whose PSNR is higher than haar-based MCTF keep more approximate information of original frames.
