Temporal frame interpolation is an important problem in many areas of modern video processing. However the task of accurate motion estimation for temporal interpolation is an open issue. In this paper we propose a new motion estimation algorithm for motion compensated frame interpolation. The developed algorithm is consistent with the conventional model of true motion and can be considered as a method of local minimization for the optimization problem defined within this model. The evaluation of the algorithm is performed for frame rate upconversion problem. Simulation results demonstrate performance comparable to existing frame rate up-conversion methods.
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.
