Abstract : Spatio-temporal motion-compensated wavelet decomposition is an increasingly popular method for scalable video coding, with coding efficiency which is competitive with state-of-the-art non-scalable codecs. In this paper, we propose a new spatio-temporal update operator in the lifting scheme allowing efficient implementation of these temporal decompositions. We demonstrate its improved performance both theoretically, by exhibiting a decrease in the reconstruction error, and by simulation results.
