Parallel Block Sequential Closed-Form Matting With Fan-Shaped Partitions.
IEEE Transactions on Image Processing(2018)
摘要
Applying alpha matting to large images is a challenging task because of its computational complexity. This paper provides a divide and conquer strategy for performing closed-form matting. The matting problem, defined for an entire image, is broken down into systems of linear equations defined for very small blocks of the image. The sizes of the small systems are small enough for us to find solutio...
