Abstract

Aspects of the present invention are related to systems and methods for reducing compression artifacts. Decoded and displayed images and videos that have been compressed may exhibit visually objectionable artifacts. Aspects of the present invention relate to methods and systems for reducing visible artifacts by selectively filtering an image region based on a combination of a motion indicator and an edge-strength indicator.
