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…
Compressed sensing with structured sparsity and structured acquisition
Claire Boyer, Jérémie Bigot, Pierre Weiss
Compressed Sensing (CS) is an appealing framework for applications such as Magnetic Resonance Imaging (MRI). However, up-to-date, the sensing schemes suggested by CS theories are m…
Variable density sampling based on physically plausible gradient waveform. Application to 3D MRI angiography
Nicolas Chauffert, Pierre Weiss, Marianne Boucher +2
Performing k-space variable density sampling is a popular way of reducing scanning time in Magnetic Resonance Imaging (MRI). Unfortunately, given a sampling trajectory, it is not c…
