Abstract:A new method to recognize human activity with videos from a wearable camera is proposed in this paper. With a camera mounted to a human body, the moving subject won't appear in the video when the person is in some motions. But we can estimate the activity from the changes of scenes in videos. Optical flow method is a common method to calculate motion vectors of objects in two adjacent images. For higher precision, in this paper, we use Lucas-Kanade optical flow method with pyramid structure to calculate the op… 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.
