A topological analysis on patches of optical flow. (English) Zbl 1329.62298
Summary: The research of optical flow is vitally important topic in computer vision. In this paper we research a topological analysis of space of optical flow locally. We use the methods of computing topology to the spaces of \(4\times 4\) and \(6 \times 6\) high contrast optical flow patches. We experimentally prove that in both cases there exist subspaces of the spaces of all high contrast optical flow patches that is topologically equivalent to a circle, which states that some results on the topological analysis of natural images and range images can be extended to the scope of image motion.
