On the Recursions of Robust COMET Algorithm for Convexly Structured Shape Matrix

This paper addresses robust estimation of structured shape (normalized covariance) matrices. Shape matrices most often own a particular structure depending on the application of interest and taking this structure into account improves estimation…

3D Tomography back-projection parallelization on Intel FPGAs using OpenCL

This article deals with the evaluation of FPGAs resurgence for hardware acceleration applied to computed tomography on the back-projection operator used in iterative reconstruction algorithms. We focus our attention on the tools developed by FPGAs…

An Improved Low Rank Detector in the High Dimensional Regime

This paper introduces an improved Low Rank Adaptive Normalized Matched Filter (LR-ANMF) detector in a high dimensional (HD) context where the observation dimension is large and of the same order of magnitude than the sample size. To that end, the…

Thermal simulations of SiC MOSFETs under short- circuit conditions: influence of various simulation parameters

The temperature distribution in a Silicon Carbide (SiC) MOSFET during a destructive short-circuit is simulated using a custom 1D-finite difference model implemented using Matlab. Some of the main assumptions usually put forward in the literature…

Track-Before-Detect Framework-Based Vehicle Monocular Vision Sensors

This paper proposes a Track-before-Detect framework for a multibody motion segmentation (named TbD-SfM). Our contribution relies on a tightly coupled tracking before detection strategy intended to reduce the complexity of existing Multibody…
