Gradient waveform design for variable density sampling in Magnetic Resonance Imaging
Nicolas Chauffert, Pierre Weiss, Jonas Kahn +1
Fast coverage of k-space is a major concern to speed up data acquisition in Magnetic Resonance Imaging (MRI) and limit image distortions due to long echo train durations. The hardw…
Hyperspectral pan-sharpening: a variational convex constrained formulation to impose parallel level lines, solved with ADMM
Alexis Huck, François de Vieilleville, Pierre Weiss +1
In this paper, we address the issue of hyperspectral pan-sharpening, which consists in fusing a (low spatial resolution) hyperspectral image HX and a (high spatial resolution) panc…
Sparse Wavelet Representations of Spatially Varying Blurring Operators
Paul Escande, Pierre Weiss
Restoring images degraded by spatially varying blur is a problem encountered in many disciplines such as astrophysics, computer vision or biomedical imaging. One of the main challe…
