On spatial resolution, signal-to-noise and information capacity of linear imaging systems
Timur Gureyev, Yakov Nesterets, Frank de Hoog
A simple model for image formation in linear shift-invariant systems is considered, in which both the detected signal and the noise variance are varying slowly compared to the poin…
Evaluating the Performance of BSBL Methodology for EEG Source Localization On a Realistic Head Model
Sajib Saha, Rajib Rana, Ya. I. Nesterets +3
Source localization in EEG represents a high dimensional inverse problem, which is severely ill-posed by nature. Fortunately, sparsity constraints have come into rescue as it helps…
Linear algorithms for phase retrieval in the Fresnel region: validity conditions
T. E. Gureyev, Ya. I. Nesterets
We describe the relationship between different forms of linearized expressions for the spatial distribution of intensity of X-ray projection images obtained in the Fresnel region.…
Sparse Bayesian Learning for EEG Source Localization
Sajib Saha, Frank de Hoog, Ya. I. Nesterets +3
Purpose: Localizing the sources of electrical activity from electroencephalographic (EEG) data has gained considerable attention over the last few years. In this paper, we propose…
