Inventor: CHANG TSUISHAN
IPC: H04N19/00
Filed: 2019-06-20
Abstract: Systems and methods are provided for implementing inter-coded resolution-adaptive video coding supported by multiple in-loop filters, restoring high-frequency loss that occurs when a picture is down-sampled and subsequently up-sampled, and improving image quality during a resolution-adaptive video coding process. The methods and systems described herein provide a deblocking filter which takes resolution changes of a frame into account in determining filter strength; a sample adaptive offset (SAO) filter which flexibly applies edge offset to leverage its utility for restoring high-frequency loss, and identify strong edges and apply offsets to compensate loss of detail during down-sampling and up-sampling; and a broadened selection of adaptive loop filter (ALF) coefficients which provide finer granularity for compensating for high-frequency loss.
