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

An improved Richardson–Lucy algorithm based on local prior
TL;DR: This paper improves the RL algorithm based on the local prior to suppress the ringing artifacts caused by failures in the blur kernel estimation, and shows that high-quality deblurred images can be obtained even when the estimated kernels are not perfectly accurate.

Improving space debris detection in GEO ring using image deconvolution
TL;DR: A method based on image deconvolution to improve the detection of space debris, mainly in the geostationary ring, and the iterative Richardson–Lucy (R–L) method, as the method that achieves better goals with a reasonable amount of computation is presented.

A synthesis route of gold nanoparticles without using a reducing agent
TL;DR: In this article, a microwave-assisted technique was proposed to synthesize gold nanoparticles (NPs) without the need of adding any reducing agent, only water and the gold salt precursor are necessary to generate the NPs under the influence of microwaves.

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.
