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 $ℓ^{1}$ -- $ℓ^{2}$ 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…
