Nonlocal Inpainting of Manifold-valued Data on Finite Weighted Graphs. (arXiv:1704.06424v1 [math.NA])
来源于:arXiv
Recently, there has been a strong ambition to translate models and algorithms
from traditional image processing to non-Euclidean domains, e.g., to
manifold-valued data. While the task of denoising has been extensively studied
in the last years, there was rarely an attempt to perform image inpainting on
manifold-valued data. In this paper we present a nonlocal inpainting method for
manifold-valued data given on a finite weighted graph. We introduce a new graph
infinity-Laplace operator based on the idea of discrete minimizing Lipschitz
extensions, which we use to formulate the inpainting problem as PDE on the
graph. Furthermore, we derive an explicit numerical solving scheme, which we
evaluate on two classes of synthetic manifold-valued images. 查看全文>>
