A closed-form solution to video matting of natural snow
In this paper, we address the problem on video matting of natural snow in snowing context. By optical features of natural snow and the continuity of a video, we design a suitable temporal filter to recover the background of the video and compute the approximate matte gradient. Using two types of information obtained, we first propose a closed-form solution to video matting of natural snow. (C) 2009 Elsevier B.V. All rights reserved.
