COL0RME: Super-resolution microscopy based on sparse blinking/fluctuating fluorophore localization and intensity estimation

Vasiliki Stergiopoulou, Luca Calatroni, José Henrique de Morais Goulart +2

To overcome the physical barriers caused by light diffraction, super-resolution techniques are often applied in fluorescence microscopy. State-of-the-art approaches require specifi…

A cortical-inspired sub-Riemannian model for Poggendorff-type visual illusions

Emre Baspinar, Luca Calatroni, Valentina Franceschi +1

We consider Wilson-Cowan-type models for the mathematical description of orientation-dependent Poggendorff-like illusions. Our modelling improves two previously proposed cortical-i…

COL0RME: COvariance-based super-Resolution Microscopy with intensity Estimation

Vasiliki Stergiopoulou, José Henrique de Morais Goulart, Sébastien Schaub +2

Super-resolution light microscopy overcomes the physical barriers due to light diffraction, allowing for the observation of otherwise indistinguishable subcellular entities. Howeve…

Accelerated iterative regularization via dual diagonal descent

Luca Calatroni, Guillaume Garrigos, Lorenzo Rosasco +1

We propose and analyze an accelerated iterative dual diagonal descent algorithm for the solution of linear inverse problems with general regularization and data-fit functions. In p…

Cortical-inspired Wilson-Cowan-type equations for orientation-dependent contrast perception modelling

Marcelo Bertalmío, Luca Calatroni, Valentina Franceschi +2

We consider the evolution model proposed in [9, 6] to describe illusory contrast perception phenomena induced by surrounding orientations. Firstly, we highlight its analogies and d…

Adaptive parameter selection for weighted-TV image reconstruction problems

Luca Calatroni, Alessandro Lanza, Monica Pragliola +1

We propose an efficient estimation technique for the automatic selection of locally-adaptive Total Variation regularisation parameters based on an hybrid strategy which combines a…

Technical Report: Band selection for nonlinear unmixing of hyperspectral images as a maximal clique problem

Tales Imbiriba, José Carlos Moreira Bermudez, Cédric Richard

Kernel-based nonlinear mixing models have been applied to unmix spectral information of hyperspectral images when the type of mixing occurring in the scene is too complex or unknow…
