Closed-form matting
WebSep 16, 2024 · These approaches, which have closed-form solutions, are called closed-form matting approaches. This paper provides an extensive overview on the closed-form matting theory. A hierarchical matting model is presented, classifying affinity-based approaches into three categories. The basis of each model and the relationships … WebClosed-Form Matting and Astrophotography.

WebAug 2, 2013 · In this paper, we present a unified acceleration method for closed-form image and video matting using a hierarchical data structure, which achieves an … Webclosed form formula allows us to predict the properties of the solution by analyzing the eigenvectors of a sparse ma-trix, closely related to matrices used in spectral image seg-mentation algorithms. We show that high quality mattes can be obtained on natural images from a surprisingly small amount of user input. 1. Introduction
WebSep 17, 2016 · Levin et al. [ 1] developed closed-form matting by defining matting Laplacian under the color-line model. It updates to cluster-based spectral matting in [ 21 ]. To accelerate matting Laplacian computation, He et al. [ 22] computed the large-kernel Laplacian. Assuming intensity change locally smooth, Sun et al. [ 23] proposed Poisson … WebPeople MIT CSAIL
