Scalable photoacoustic tomography implementations accounting for the spatial impulse response of transducers
Trung-Thai Do, Paul Escande, Caroline Chaux +2
Iterative model-based reconstruction in photoacoustic tomography repeatedly applies the forward operator mapping the initial pressure to the transducer signals, and its adjoint. At…
Deep Unrolling for Nonconvex Robust Principal Component Analysis
Elizabeth Z. C. Tan, Caroline Chaux, Emmanuel Soubies +1
We design algorithms for Robust Principal Component Analysis (RPCA) which consists in decomposing a matrix into the sum of a low rank matrix and a sparse matrix. We propose a deep…
Straight-Through meets Sparse Recovery: the Support Exploration Algorithm
Mimoun Mohamed, François Malgouyres, Valentin Emiya +1
The {\it straight-through estimator} (STE) is commonly used to optimize quantized neural networks, yet its contexts of effective performance are still unclear despite empirical suc…
Unmixing 2D HSQC NMR mixtures with -NMF and sparsity
Afef Cherni, Sandrine Anthoine, Caroline Chaux
Nuclear Magnetic Resonance (NMR) spectroscopy is an efficient technique to analyze chemical mixtures in which one acquires spectra of the chemical mixtures along one ore more dimen…
Phase inpainting in time-frequency plane
A. ~Marina Krémé, Valentin Emiya, Caroline Chaux
We propose a new problem of missing data reconstruction in the time-frequency plane. This problem called phase inpainting, consists in reconstructing a signal from time-frequency o…
Image Analysis Using a Dual-Tree -Band Wavelet Transform
Caroline Chaux, Laurent Duval, Jean-Christophe Pesquet
We propose a 2D generalization to the -band case of the dual-tree decomposition structure (initially proposed by N. Kingsbury and further investigated by I. Selesnick) based on…
