Point Spread Function Estimation in X-ray Imaging with Partially Collapsed Gibbs Sampling
Kevin T. Joyce, Johnathan M. Bardsley, Aaron Luttman
The point spread function (PSF) of a translation invariant imaging system is its impulse response, which cannot always be measured directly. This is the case in high energy X-ray r…

Improved Probabilistic Principal Component Analysis for Application to Reduced Order Modeling
Indika Udagedara, Brian Helenbrook, Aaron Luttman +1
In our previous work, a reduced order model (ROM) for a stochastic system was made, where noisy data was projected onto principal component analysis (PCA)-derived basis vectors to…
