Bayesian-Based Iterative Method of Image Restoration
TLDR
An iterative method of restoring degraded images was developed by treating images, point spread functions, and degraded images as probability-frequency functions and by applying Bayes’s theorem.Abstract:
An iterative method of restoring degraded images was developed by treating images, point spread functions, and degraded images as probability-frequency functions and by applying Bayes’s theorem. The method functions effectively in the presence of noise and is adaptable to computer operation.read more

TL;DR: In this article, the authors derived the complex morphology of the molecular clouds and the circumnuclear disk, along with their masses (of order 105-106 M ) and derived also the temperature and spectral index maps of the regions under study.

Quantitative Convergent Beam Electron Diffraction
TL;DR: In this article, the authors introduced quantitative convergent-beam electron diffraction from quantitative X-ray diffraction intensity recording to quantitative structural retrieval, which can be obtained from experimental diffraction intensities by optimization of structural parameters in a theoretical model.

Flash light detection and ranging range accuracy limits for returns from single opaque surfaces via Cramer-Rao bounds
TL;DR: A Cramer-Rao lower bound on the range accuracy obtainable by a Flash light detection and ranging (LADAR) system receiving a return from a single surface in the instantaneous field of view of each detector is developed and verified with experimental data.

Modern probability theory and its applications
TL;DR: Probability Theory as the study of Mathematical Models of Random Phenomena as mentioned in this paper is a generalization of probability theory for the study and analysis of statistical models of random variables.

Image Evaluation and Restoration
TL;DR: The extent to which the processing approaches the optimum can be evaluated by determining the fraction of the total information content of the image which can be visually extracted after processing.

Restoration of Turbulence-Degraded Images*
TL;DR: In this paper, the amplitude and phase coefficients of the two-dimensional Fourier series representing the degraded images were corrected by applying corrections to the optical transfer function of the turbulence measured at the time the images were photographed.
