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…
On 1-Laplacian Elliptic Equations Modeling Magnetic Resonance Image Rician Denoising
Adrian Martin, Emanuele Schiavi, Sergio Segura de Leon
Modeling magnitude Magnetic Resonance Images (MRI) rician denoising in a Bayesian or generalized Tikhonov framework using Total Variation (TV) leads naturally to the consideration…
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…
A Multicomponent Approach to Nonrigid Registration of Diffusion Tensor Images
Mohammed Khader, A. Ben Hamza
We propose a nonrigid registration approach for diffusion tensor images using a multicomponent information-theoretic measure. Explicit orientation optimization is enabled by incorp…
