Spatio-temporal differentiation method is one of the most effective methods of determining the velocity of moving objects. However, the optical flow estimate takes long time so that real-time object tracking is difficult to realize. In this study, we evaluated consuming time of the optical flow estimation when calculating in parallel. The method of parallelization includes dividing input image into several region and assigning each region into each multi-core. Because spatio-temporal differentiation method is…
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.
