Temporally coherent video matting
Existing video matting approaches determine the alpha matte sequence frame-by-frame, which lead to flickering near the boundary of the foreground region. We reduce this effect by considering video data as a spatio-temporal cube, and extending a robust matting algorithm to a 3D solver. Our results demonstrate consistent and visually pleasing alpha mattes, and tend to preserve temporal coherence better than previous techniques.
