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 the case of Pluto and Charon, the most distant objects so mapped, a unique feature of the Pluto imaging data set is the observation of terrains illuminated only by light scattered from atmospheric haze, allowing us to map terrains in the southern hemisphere that would otherwise have been in darkness.

X-ray scatter correction for cone-beam CT using moving blocker array
TL;DR: In this paper, an array of moving blockers has been developed to combine accurate scatter estimation and reconstruction into one single scan, where the blocker array moves from projection to projection, such that every detector pixel is not consecutively blocked during the data acquisition, and the missing primary data in the blocker shadows are estimated by interpolation.

Bayesian deconvolution for angular super-resolution in forward-looking scanning radar.
TL;DR: Experimental results demonstrate that the proposed deconvolution algorithm has higher precision for angular super-resolution compared with the conventional algorithms, such as the Tikhonov regularization algorithm, the Wiener filter and the Richardson–Lucy algorithm.

Lensfree fluorescent on-chip imaging of transgenic Caenorhabditis elegans over an ultra-wide field-of-view.
TL;DR: This first time that a lensfree on-chip platform has successfully imaged fluorescent C. elegans on a chip over an ultra-wide field-of-view (FOV) of e.g., >2–8 cm2 with a spatial resolution of ∼10µm is demonstrated.

TL;DR: In this article, the prototypical isolated Bok globule with an embedded protostar was observed using infrared and millimeter observations of Barnard 335, and the authors measured the source luminosity accurately; they also constrain the density profile of the innermost globule material near the protostars using the observation of an 80 m shadow.

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.
