WebMar 11, 2024 · Abstract: We observe a common characteristic between the classical propagation-based image matting and the Gaussian process (GP)-based regression. The former produces closer alpha matte values for pixels associated with a higher affinity, while the outputs regressed by the latter are more correlated for more similar inputs.

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.
