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

Modified version of the Chahine algorithm to invert spectral extinction data for particle sizing
TL;DR: A modified version of the nonlinear iterative Chahine algorithm is presented and applied to the inversion of spectral extinction data for particle sizing, showing that distributions and sample concentrations can be recovered to a high degree of accuracy when the indices of refraction of the sample and of the solvent are known.

Blind-deconvolution optical-resolution photoacoustic microscopy in vivo.
TL;DR: The development of blind-deconvolution optical-resolution photoacoustic microscopy (BD-PAM) that can provide a lateral resolution ~2-fold finer than that of conventional OR-Pam (3.04 vs. 5.78μm), without physically increasing the system's numerical aperture is reported.

TL;DR: In this article, the authors used the Wide Field and Planetary Camera 2, the Advanced Camera for Surveys and the Space Telescope Imaging Spectrograph to image and spectroscopic observations of three Brightest Cluster Galaxies (Abell 1836-BCG, Abell 2052 -BCG and Abell 3565-BCGs) with the Hubble Space Telescope.

The dark-matter fraction in the elliptical galaxy lensing the quasar pg 1115+080
David Pooley,Saul Rappaport,Jeffrey A. Blackburne,Paul L. Schechter,Josiah Schwab,Joachim Wambsganss,Joachim Wambsganss +6 more
TL;DR: In this article, the authors determined the most likely dark-matter fraction in the elliptical galaxy quadruply lensing the quasar PG 1115+080 based on analyses of the X-ray fluxes of the individual images in 2000 and 2008.

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.
