Nonparametric sampling can accelerate the video-matting process from minutes to seconds per frame. In addition, a super-resolution technique efficiently bridges the gap between mattes from high-resolution video cameras and those from low-resolution cameras. Off-center matting pulls mattes for an external high-resolution camera that doesn{\textquoteright}t share the same center of projection as the low-resolution cameras used to capture the defocus matting data. In this article, we address these limitations and extend defocus matting in several important ways}, author = {N. Joshi and Matusik, W. and Avidan, S. and H. Pfister and Freeman, W.T.} }
