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

Quantitative Surface Crack Evaluation Based on Eddy Current Pulsed Thermography
TL;DR: In this paper, a post-image segmentation algorithm is proposed based on the idea of grouping histogram and iterative adaption approach that leads to better performance for quantitatively identifying and sizing the defect.

Stray light correction and contrast analysis of Hinode broad-band images
TL;DR: In this paper, the contrasts of features in the quiet Sun are studied using filtergrams recorded by the broad-band filter imager mounted on the Hinode/Solar Optical Telescope.
Journal ArticleDOI
Image gathering and processing for enhanced resolution
TL;DR: In this article, the authors consider a class of problems in which the total available spatial bandwidth is fixed but the location of this bandwidth along the spatial-frequency axis is to some extent under our control.

A Chandra View of the Morphological and Spectral Evolution of Supernova Remnant 1987A
TL;DR: In this paper, the authors present an update on the results of their monitoring observations of the X-ray remnant of supernova 1987A with Chandra, which allows them to monitor the details of the earliest stage of the supernova remnant evolution in X-rays.

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.
