This paper proposes a frame level rate control scheme for HEVC based on support vector machine. Firstly, textual features of frames are extracted from video sequence. According to different complexities of textual features, support vector machine is chosen as a classifier for video classification. Secondly, a frame level rate control scheme is proposed to achieve higher coding efficiency based on classification results. According to the experiment results, the proposed algorithm achieves better coding performance than the original rate control scheme JCTVC -K0103 in HEVC.
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.
