Non-convex non-local flows for saliency detection
Iván Ramírez, Gonzalo Galiano, Emanuele Schiavi
We propose and numerically solve a new variational model for automatic saliency detection in digital images. Using a non-local framework we consider a family of edge preserving fun…
Well-posedness of a nonlinear integro-differential problem and its rearranged formulation
Gonzalo Galiano, Emanuele Schiavi, Julián Velasco
We study the existence and uniqueness of solutions of a nonlinear integro-differential problem which we reformulate introducing the notion of the decreasing rearrangement of the so…
On a new formulation of nonlocal image filters involving the relative rearrangement
Gonzalo Galiano, Julián Velasco
Nonlocal filters are simple and powerful techniques for image denoising. In this paper we study the reformulation of a broad class of nonlocal filters in terms of two functional re…
Neighborhood filters and the decreasing rearrangement
Gonzalo Galiano, Julián Velasco
Nonlocal filters are simple and powerful techniques for image denoising. In this paper, we give new insights into the analysis of one kind of them, the Neighborhood filter, by usin…
