  • Removal of block encoding artifacts
    Patent number: 7003174
    Abstract: A method of reducing artifacts in an image previously processed by block transform encoding may comprise the steps of: determining block boundaries; determining an approximate metric of artifact visibility; optionally interpolating across block boundaries; adaptively filtering luminance; optionally adaptively filtering chrominance; adaptively adjusting local saturation variation; and adaptively simulating high spatial frequency image detail; wherein the adaptive steps are executed to an extent or in an amount depending on the metric or standard or measurement of artifact visibility.
