Abstract:To enhance the DGDS algorithm, this paper presents an efficient algorithm named modified directional gradient descent searches (MDGDS). By analyzing the statistical best MV distribution on some well-known test video sequences, a new search pattern is derived with three search rounds including the window center area, cross area and diagonal area based on stationery and quasi-stationery characteristics. Early search termination operations are then applied to the new search pattern before performing DGDS to elimi… 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.
