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. Splet31. mar. 2024 · Empowered by Matting Laplacian training loss which can address the pixel affinity loss problem led by the linear transform, the proposed framework is applicable and effective on versatile style transfer. Extensive experiments show that CAP-VSTNet can produce better qualitative and quantitative results in comparison with the state-of-the-art ...
Splet1) The Matting Laplacian: The matting Laplacian was introduced by Levin et al. [14] in order to evaluate the quality of a matte without explicitly estimating the foreground and … Splet28. jun. 2013 · In this paper we propose a novel alpha matting method with local and nonlocal smooth priors. We observe that the manifold preserving editing propagation [4] essentially introduced a nonlocal smooth prior on the alpha matte. This nonlocal smooth prior and the well known local smooth prior from matting Laplacian complement each …
