Evaluation of Blur and Gaussian Noise Degradation in Images Using Statistical Model of Natural Scene and Perceptual Image Quality Measure [PDF]

Radioengineering, 2017
In this paper we present new method for classification of image degradation type based on Riesz transform coefficients and Blind/Referenceless Image Spatial Quality Evaluator (BRISQUE) that employs spatial coefficients.

A New Full-Reference Image Quality Metric for Motion Blur Profile Characterization

IEEE Access, 2021
Motion blur is common in images captured by handheld devices, arising from hand, device and/or object motion. To restore sharp images from the images degraded by the motion, it is extremely important to assess the quality of the captured image and its ...

Image Enhancement Techniques for Images at Blur Motion and Different Noises [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2019
Image restoration is an art to improve image quality by disposing of reducing the amount of noise and blurring present in the image. So it is one of the research titles of interest to the researchers.

Blur detection is unaffected by cognitive load [PDF]

, 2014
Blur detection is affected by retinal eccentricity, but is it also affected by attentional resources? Research showing effects of selective attention on acuity and contrast sensitivity suggests that allocating attention should increase blur detection ...

Calibration features of information-measuring systems for diagnosing technical condition based on the analysis of the mark image blurring

Известия высших учебных заведений. Поволжский регион:Технические науки, 2023
Background. The necessity of creating diagnostic systems for vibro-loaded objects is shown. Contactless systems have sufficient capabilities to determine the amplitude of vibrations, it is noted that an important part of such systems is the calibration ...

Joint Blind Motion Deblurring and Depth Estimation of Light Field

, 2018
Removing camera motion blur from a single light field is a challenging task since it is highly ill-posed inverse problem. The problem becomes even worse when blur kernel varies spatially due to scene depth variation and high-order camera motion.

Myopia and defocus: the current understanding [PDF]

, 2011
The current theories relating to the development and progression of myopia are related to exposure of the eye to hyperopic defocus. This paper discusses these theories and the large body of recent research investigating the evidence behind them.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...
