Abstract

Three-dimensional (3-D) subband/ wavelet coding via a Motion Compensated Temporal Filter (MCTF) is emerging as a very effective structure for highly scalable video coding. In this paper, a low bit rate video coding system based on three dimensional (3-D) wavelet coding using longer filters (Le Gall 5/3, 9/7) is implemented for Telemedicine imaging applications. In addition, a new scheme for finding the motion vectors (MV) is proposed and through several experimental results, it has been observed that it outperforms H.264 base line profile in terms of PSNR.
