Abstract

Defocus 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 highresolution 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 lowresolution cameras used to capture the defocus matting data.
