Non-parametric PSF estimation from celestial transit solar images using blind deconvolution
Adriana Gonzalez, Véronique Delouille, Laurent Jacques
Context: Characterization of instrumental effects in astronomical imaging is important in order to extract accurate physical information from the observations. The measured image i…
Proceedings of the second "international Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST'14)
L. Jacques, C. De Vleeschouwer, Y. Boursier +64
The implicit objective of the biennial "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) is to foster collaboration between interna…
Robust Phase Unwrapping by Convex Optimization
Adriana Gonzalez, Laurent Jacques
The 2-D phase unwrapping problem aims at retrieving a "phase" image from its modulo observations. Many applications, such as interferometry or synthetic aperture radar imaging…
Compressive Imaging and Characterization of Sparse Light Deflection Maps
Prasad Sudhakar, Laurent Jacques, Xavier Dubois +2
Light rays incident on a transparent object of uniform refractive index undergo deflections, which uniquely characterize the surface geometry of the object. Associated with each po…
Error Decay of (almost) Consistent Signal Estimations from Quantized Gaussian Random Projections
Laurent Jacques
This paper provides new error bounds on "consistent" reconstruction methods for signals observed from quantized random projections. Those signal estimation techniques guarantee a p…
Quantization and Compressive Sensing
Petros T. Boufounos, Laurent Jacques, Felix Krahmer +1
Quantization is an essential step in digitizing signals, and, therefore, an indispensable component of any modern acquisition system. This book chapter explores the interaction of…
