Four-Dimensional Anisotropic Diffusion Framework With PDEs for Light Field Regularization and Inverse Problems
Autor: Pierre Allain, Christine Guillemot, Laurent Guillo
Publikováno v: IEEE Transactions on Computational Imaging. 6:109-124
In this paper, we consider the problem of vector-valued regularization of light fields based on PDEs. We propose a regularization method operating in the four-dimensional (4-D) ray space that does not require prior estimation of disparity maps. The m

Liver tissue changes during and post 6-month spaceflight as measured by ultrasound radio frequency signal processing
Autor: Philippe Arbeille, Kathryn Zuj, Laurent Guillon
Publikováno v: Frontiers in Physiology, Vol 15 (2024)
BackgroundAnalysis of ultrasound radio frequency (RF) signals allows for the determination of the index of reflectivity (IR), which is a new measure that is dependent on tissue properties. Previous work has shown differences in the IR of the carotid
