Parallel Block Sequential Closed-Form Matting With Fan-Shaped Partitions

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 ve...
