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.
