Abstract
This paper proposes a novel video coding scheme based on combination of motion compensation and wave form coding. In order to realize appropriate bit-allocation to both motion compensation and wave form coding, we employ a waveform coding algorithm called matching pursuits which can freely control a coding rate of motion compensated frame differences. Moreover we develop an iterative motion compensation method which can successively improve quality of reconstructed images, and combine it with the above matching pursuits seamlessly and adaptively. In other words, motion compensation and matching pursuits are carried out repeatedly in the order of decreasing coding efficiency. Simulation results indicate that the proposed coding scheme shows SNR gains of 0.5-1.3 dB over the H.263 standard for typical QCIF sequences.
