Fast algorithms for hyperspectral Diffuse Optical Tomography
Arvind K. Saibaba, Misha Kilmer, Eric Miller +1
The image reconstruction of chromophore concentrations using Diffuse Optical Tomography (DOT) data can be described mathematically as an ill-posed inverse problem. Recent work has…
Fast Kalman Filter using Hierarchical-matrices and low-rank perturbative approach
Arvind K. Saibaba, Eric Miller, Peter K. Kitanidis
We develop a fast algorithm for Kalman Filter applied to the random walk forecast model. The key idea is an efficient representation of the estimate covariance matrix at each time-…
Stabilizing dual-energy X-ray computed tomography reconstructions using patch-based regularization
Brian H. Tracey, Eric L. Miller
Recent years have seen growing interest in exploiting dual- and multi-energy measurements in computed tomography (CT) in order to characterize material properties as well as object…
