Stochastic Quasi-Fej\'er Block-Coordinate Fixed Point Iterations With Random Sweeping II: Mean-Square and Linear Convergence
TL;DR: Results on the mean-square and linear convergence of the iterates of the block-coordinate fixed point algorithms are established and applications to monotone operator splitting and proximal optimization algorithms are presented.
Proceedings Article
ℓ 1 -adapted non separable vector lifting schemes for stereo image coding
TL;DR: A two-dimensional non separable decomposition based on the concept of vector lifting scheme is proposed, which focuses on the optimization of all the lifting operators employed with the left and right images.
Proceedings ArticleDOI
A Moment-Based Approach for Guaranteed Tensor Decomposition
TL;DR: This paper presents a new scheme to perform the canonical polyadic decomposition (CPD) of a symmetric tensor as a truncated moment problem, where a measure has to be recovered knowing some of its moments.
Proceedings ArticleDOI
A Hybrid Interior Point - Deep Learning Approach for Poisson Image Deblurring
TL;DR: This paper addresses the problem of deconvolution of an image corrupted with Poisson noise by reformulating the restoration process as a constrained minimization of a suitable regularized data fidelity function.
Proceedings ArticleDOI
Multiscale detection of nonstationary signals
TL;DR: In this paper, a statistical method for detecting and/or localizing nonstationarities in a process observed over a time interval T is presented, where stationarity is induced by taking a wavelet transform of the process.
