Low-l CMB Analysis and Inpainting
J. -L. Starck, M. J. Fadili, A. Rassat
Reconstruction of the CMB in the Galactic plane is extremely difficult due to the dominant foreground emissions such as Dust, Free-Free or Synchrotron. For cosmological studies, th…
A quasi-Newton proximal splitting method
Stephen Becker, M. Jalal Fadili
A new result in convex analysis on the calculation of proximity operators in certain scaled norms is derived. We describe efficient implementations of the proximity calculation for…
Stabilizing Nonuniformly Quantized Compressed Sensing with Scalar Companders
L. Jacques, D. K. Hammond, M. J. Fadili
This paper studies the problem of reconstructing sparse or compressible signals from compressed sensing measurements that have undergone nonuniform quantization. Previous approache…
Risk estimation for matrix recovery with spectral regularization
Charles-Alban Deledalle, Samuel Vaiter, Gabriel Peyré +2
In this paper, we develop an approach to recursively estimate the quadratic risk for matrix recovery problems regularized with spectral functions. Toward this end, in the spirit of…
True CMB Power Spectrum Estimation
P. Paykari, J. L. Starck, M. J. Fadili
The cosmic microwave background (CMB) power spectrum is a powerful cosmological probe as it entails almost all the statistical information of the CMB perturbations. Having access t…
