Abstract

Method and apparatus are described wherein a filtered reconstructed image block from a prediction block and a reconstructed prediction residual is obtained and a Quantization Constrained correction is applied to the filtered reconstructed image block, wherein the Quantization Constrained correction applied depends on whether at least one part of transformed coefficients decoded for the image block have been zeroed out during encoding of the image block. In some embodiments, QC correction is skipped for these transformed coefficients. In some variants, scanning of the transformed coefficients is adapted for the image block.
