Wavelet Based Lossless Video Compression Using Motion Compensated Temporal Filtering

Abstract

In the paper we propose a new lossless video coding system utilizing both Motion Compensated Temporal Filtering (MCTF) and integer wavelet transform techniques to explore data redundancy in both spatial and temporal domain, respectively. We elaborate the design issues such MCTF scheme, filter selection, group of picture size, wavelet coefficient coding, and develop an efficient coding system. Simulation results show that the proposed system using 1/3 filter has the best coding performance. The bit rate saving is over 20% compared with lossless still image coder such as JPEG-LS. The saving is also around 10% when compared with other wavelet based lossless video coder.
