This paper presents a new design criterion in order to make the multiresolution filter banks perform the best quality/compression ratio, in the frame of scene adaptive coding. The optimization adapts the filters parameters to the codec features and to the statistics of 2-D sources. The aim of the paper is the comparison of several multiresolution linear transforms implemented by separable FIR filter banks. Some of them are well-known transforms while others are optimized in the light of our criterion. Objective criterions and visual tests are taken into consideration.
