Bruno Paillard, J. Soumagne, P. Mabilleau, S. Morissette · 2005
The following paper discusses a vectorial description of the subband decomposition/ reconstruction process and shows its advantages compared to the usual description. The following points are examined:\bulletnecessary and sufficient conditions for exact reconstruction,\bulletreconstruction error measure,\bulletinteresting properties of exact reconstruction processes, and comparison between transform coding and subband coding.
