Closed-form matting
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 WebA closed-form solution to natural image matting. IEEE Trans.
