A POCS-Based Algorithm for Blocking Artifacts Reduction

Introduction Block-based discrete cosine transform(BDCT) is considered to be a basic tool in bothstill and moving image compression standards,such as JPEG, H.261/263, and MPEG, owing toits near-optimal energy compaction property andmoderate hardware complexity. However, sinceeach N×N block is coded independently, the re-constructed images would exhibit annoying discon-tinuities along block boundaries at low bit rate,which are often referred to as the“blocking arti-facts”in the transfo…
