Spatial resolution, noise and information in the computational-imaging era
David M. Paganin, Alexander Kozlov, Timur E. Gureyev
Imaging is an important means by which information is gathered regarding the physical world. Spatial resolution and signal-to-noise ratio are underpinning concepts. There is a pauc…
Noise-resolution uncertainty principle in classical and quantum systems
Timur E. Gureyev, Alexander Kozlov, Yakov I. Nesterets +2
It is proved that the width of a function and the width of the distribution of its values cannot be made arbitrarily small simultaneously. In the case of ergodic stochastic process…
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.…
