Abstract:This paper describes an optical-flow processor core for real-time video recognition. The processor is based on the Pyramidal Lucas and Kanade algorithm. It has small chip area, a high pixel rate, and high accuracy compared to conventional optical-flow processors. Introduction of search range limitation and the Carman filter to the original algorithm improves the optical-flow accuracy and reduces the processor hardware cost. Furthermore, window interleaving and window overlap methods can reduce the necessary cl… 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.
