The conventional Harris algorithm for comer detection, though with high reliability and strong stability, is unable to meet the requirement of the real-time system. Focus on the problem of the great amount of calculating when extracting corners on the image, this paper proposes a reduction algorithm based on Harris algorithm as follows. In order to reduce the amount of calculating and improve real-time performance of the system, we filter the pixels across the image before other steps, that is establish a thr…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
