Abstract:This paper presents the Grouping of Modes based on Random Forest (GM-RF), a fast decision algorithm for the AOMedia Video 1 (AV1) intra-frame prediction applying machine learning (ML). AV1 implements a wide variety of intra-frame prediction tools, significantly increasing the required computational effort. The GM-RF uses trained Random Forest (RF) models to reduce the number of intra-frame prediction modes evaluated for each encoded block. Experimental results show that the GM-RF achieves an average time savin… 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.
