Optimal Transport Approximation of 2-Dimensional Measures
Frédéric de Gournay, Jonas Kahn, Léo Lebrat +1
We propose a fast and scalable algorithm to project a given density on a set of structured measures defined over a compact 2D domain. The measures can be discrete or supported on c…
Approximation of integral operators using convolution-product expansions
Paul Escande, Pierre Weiss
We consider a class of linear integral operators with impulse responses varying regularly in time or space. These operators appear in a large number of applications ranging from si…
Real-time -- deblurring using wavelet expansions of operators
Paul Escande, Pierre Weiss
Image deblurring is a fundamental problem in imaging, usually solved with com-putationally intensive optimization procedures. We show that the minimization can be significantly acc…
A projection algorithm on measures sets
Nicolas Chauffert, Philippe Ciuciu, Jonas Kahn +1
We consider the problem of projecting a probability measure on a set of Radon measures. The projection is defined as a solution of the following variational pr…
