Abstract
A method for low bit rate video coding based on successive approximation wavelet vector quantisation and overlapped block matching motion compensation is described. The main advantage of this scheme is that the most important data of the motion compensated interframe prediction error image are coded with priority. Simulation results are given to evaluate the performance of the coding system at 64 kbit/sec
