Abstract:Block-based video codecs such as Versatile Video Coding (VVC)/H.266, High Efficiency Video Coding (HEVC)/H.265, Advanced Video Coding (AVC)/H.264 etc. inherently introduces compression artifacts. Although these codecs have in-loop filters to correct these distortions, they are not always effective due to the complexity of the noise. Recently, deep-learning approaches emerged as a promising solution for in-loop filtering. However, most of the previous approaches were designed solely for learning from images and… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
