Multi-view shape-from-shading

A way to overcome the concave/convex ambiguity of shape-from-shading (SfS) is to use several images of an object taken from different viewpoints, instead of a single one. A computer vision pipeline co...

Depth map super-resolution from shading

Super-resolution is one of the most classical inverse problems in computer vision. Given one low-resolution and possibly noisy input image, it aims at estimating a higher-resolution and denoised image...

Preconditioning semismooth Newton methods for optimal control problems with L^1-sparsity and control constraints

PDE-constrained optimization aims at finding optimal setups for partial differential equations so that relevant quantities are minimized. Including sparsity promoting terms in the formulation of such ...

Invariance principle for the degenerate dynamic random conductance model.

After the brilliant result of Papanicolau and Varadhan (1979) in the case of bounded stationary and ergodic environments, there has been a recent upsurge in the research of quenched homogenization in ...

Muscle synergies for motor control

Abstract: A fundamental challenge in neuroscience is understanding how the central nervous system (CNS) succeeds in coordinating the many degrees-of-freedom of the musculoskeletal system to control li...

Enhanced Sanov theorem for Brownian rough paths and an application to interacting particles

We establish a Sanov type large deviation principle for an ensemble of interacting Brownian rough paths. As application a large deviations principle for the (k-layer, enhanced) empirical measure of we...

Metodi numerici per equazioni paraboliche non lineari e applicazioni

Nel seminario presento alcune tecniche numeriche basate su un approccio semi-lagrangiano per approssimare operatori parabolici non lineari eventualmente degeneri. Nel primo problema considero l'operat...

Approcci algebrici e combinatori all'integrazione di Lie

Dato un gruppo di Lie G con algebra di Lie g, la classica formula di Baker-Campbell-Hausdorff (BCH) permette di ricostruire la struttura di gruppo in un intorno dell'unità in termini dell'applicazione...

Generalized Hough transform for segmentation of X-ray Computed Tomography images

The talk presents a generalization of the Hough transform (HT) to special classes of curves: recently, algebraic geometry arguments have been applied to generalize the HT approach to algebraic curves....

Nested Group Testing Procedures and Generalized GT Problem

Group testing has its origins in the identication of syphilis in the US army during World War II. It is a useful method that has broad applications in medicine, engineering, and even in airport securi...
