Abstract:
A method is described for reconstructing a current block of a current image from at least one block of a reconstructed reference image at a different size from the size of the current image. The method comprises the steps: motion compensate the reference block with at least one interpolation filter that depends on the size of said reference image and on the size of said current image, decode, for the current block, a residue block, and reconstruct the current block from the residue block and from the motion compensated reference block.
