Voronoi video stylisation

We introduce a novel video stylisation framework based on decomposing the video volume into 3D Voronoi cells. Colour samples are taken for each cell in a video, leading to an efficient and sparse video representation. Based on the same representation, our framework affords a wide variety of artistic rendering styles. We present two families of such styles for reconstructing stylised video frames: (1) using neighbouring Voronoi cells, and (2) a derived per-frame Delaunay-like triangulation. Our framework provides a flexible foundation for automatic video stylisation that is artistically expressive and temporally coherent.
