Abstract :
Treating the temporal direction of subband-coded images has in the past involved a choice between temporal subband decomposition, which allows scalable (partial bit-stream) decoding but may reduce the coding efficiency, or motion-compensated coding, which can be more efficient but is not scalable. The authors propose a motion-compensated subband coder which preserves the scalability of the representation, and demonstrate its application in conjunction with a novel bit allocation process
