http://www.vision.jhu.edu/assets/SingarajuPAMI11.pdf Splet• Large Kernel Matting: He, Sun, & Tang (2010) propose an efficient algorithm based on a large kernel matting Laplacian. They show that the computational complexity of their method is independent of the kernel size. • Random Walk Matting: Grady, Schiwietz, Aharon, & Westermann (2005) use random walks on the pixels to estimate alpha.
