Fast Scalable Image Restoration using Total Variation Priors and Expectation Propagation
Dan Yao, Stephen McLaughlin, Yoann Altmann
This paper presents a scalable approximate Bayesian method for image restoration using total variation (TV) priors. In contrast to most optimization methods based on maximum a post…
Characterization of stilbene-d12 for neutron spectroscopy without time of flight
N. Gaughan, J. Zhou, F. D. Becchetti +4
We have experimentally characterized the light-output response of a deuterated trans-stilbene (stilbene-d12) crystal to quasi-monoenergetic neutrons in the 0.8 to 4.4 MeV energy ra…
Patch-Based Image Restoration using Expectation Propagation
Dan Yao, Stephen McLaughlin, Yoann Altmann
This paper presents a new Expectation Propagation (EP) framework for image restoration using patch-based prior distributions. While Monte Carlo techniques are classically used to s…
Sparse Linear Spectral Unmixing of Hyperspectral images using Expectation-Propagation
Zeng Li, Yoann Altmann, Jie Chen +2
This paper presents a novel Bayesian approach for hyperspectral image unmixing. The observed pixels are modeled by a linear combination of material signatures weighted by their cor…
Effect of natural gamma background radiation on portal monitor radioisotope unmixing
Matthew Weiss, Ming Fang, Yoann Altmann +2
National security relies on several layers of protection. One of the most important is the traffic control at borders and ports that exploits Radiation Portal Monitors (RPMs) to de…
