Blind Deconvolution of PET Images using Anatomical Priors
Stéphanie Guérit, Adriana González, Anne Bol +2
Images from positron emission tomography (PET) provide metabolic information about the human body. They present, however, a spatial resolution that is limited by physical and instr…
Multi-resolution Compressive Sensing Reconstruction
Adriana Gonzalez, Hong Jiang, Gang Huang +1
We consider the problem of reconstructing an image from compressive measurements using a multi-resolution grid. In this context, the reconstructed image is divided into multiple re…
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…
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 Optical Deflectometric Tomography: A Constrained Total-Variation Minimization Approach
Adriana Gonzalez, Laurent Jacques, Christophe De Vleeschouwer +1
Optical Deflectometric Tomography (ODT) provides an accurate characterization of transparent materials whose complex surfaces present a real challenge for manufacture and control.…
