Image coding by block prediction of multiresolution subimages

In this work, wepropose a coding technique that is based on the generalized blockprediction of the multiresolution subband decomposition of motioncompensated difference image frames. A segmentation mask is usedto distinguish between the regions where motion compensationwas effective and those regions where the motion model did notsucceed. The difference image is decomposed into a multiresolutionpyramid of subbands where the highest resolution subbands aredivided into two regions, based on the information given by thesegmentation mask. Only the coefficients of the regions correspondingto the motion model failure are considered in the highest resolutionsubbands. The remaining coefficients are coded using a multiresolutionvector quantization scheme that exploits inter-band non-linearredundancy. In particular, blocks in one subimage are predictedfrom blocks of the adjacent lower resolution subimage with thesame orientation. This set of blocks plays the role of a codebookbuilt from coefficients inside the subband decomposition itself.Whenever the inter-band prediction does not give satisfactoryresults with respect to a target quality, the block coefficientsare quantized using a lattice vector quantizer for a Laplaciansource.
