The deblocking filter is more complex than other modules in the H.264 because it is highly adaptive, applied to each boundary of all 4×4 blocks and updated three pixels in each direction. After careful study and analysis of this filter, we have concluded that its complexity lies in the data dependency and in the control module of elementary filters that compose it, but not in the type of these filters...
An adaptive in-loop deblocking filter (DF) is standardized in H.264/AVC to reduce blocking artifacts and improve compression efficiency. This paper proposes a low power DF architecture with hybrid and intelligent edge skip filtering order. We further adopt a four-stage pipeline to boost the speed of DF process and the proposed Horizontal Edge Skip Processing Architecture (HESPA) offers an edge skip...
