Exploring defocus matting: Nonparametric acceleration, super-resolution, and off-center matting. IEEE Computer Graphics and Applications 27(2): 43-52.0272-1716http://nrs.harvard.edu/urn-3:HUL.InstRepos:4101975Defocus matting is a fully automatic and passive method for pulling mattes from video captured with coaxial cameras that have different depths of field and planes of focus. 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't share the same center of projection as the low-resolution cameras used to capture the defocus matting data.en-USalpha matting and compositingexample-based renderingimage-based renderingvideo processingsuper-resolutionJournal Article2010-05-1910.1109/MCG.2007.32
