METHOD OF CALIBRATING A VIBRATION MEASURING SYSTEM BASED ON THE IMAGE BLUR ANALYSIS OF A ROUND TEST FRAGMENT

open access: yesМодели, системы, сети в экономике, технике, природе и обществе, 2023
Background. The purpose of this article is to improve the method of calibration of a vibration measuring system, the operation of which is based on the analysis of the image of a round test fragment with vibrational blur, by establishing a correspondence

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

open access: yesFEBS 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 ...

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

open access: yesRadioengineering, 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.

Improving defocus blur measures using robust regularization

open access: yesICT Express, 2022
This paper presents a robust regularization scheme for the enhancement of initial blur map in single image blur detection. The proposed technique considers the structural differences between guidance and initial blur map.

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Voir et entendre flou [PDF]

open access: yesSvět Literatury
Between two forms of uncertainty as non-coincidence with oneself, Cartesian imprecision and Merleau-Ponty’s blur, there is the Goethean trouble, the empirical-transcendental condition of all vision which, both sensitive and metaphysical, frees the gaze ...

Synthesis of the rotational blur kernel in a digital image using measurements of a triaxial gyroscope

open access: yesКомпьютерная оптика, 2022
A method for calculating of a blur kernel arising from the rotation of a digital camera is proposed. The rotation is measured with a three-axis gyroscope attached to the camera.

Compensating for nonstationary blurring by further blurring and deconvolution [PDF]

open access: yesInternational Journal of Imaging Systems and Technology, 2009
AbstractIn many imaging systems, the point spread function (PSF) is nonstationary. Usually, a computation‐intensive iterative algorithm is used to deblur the nonstationary PSF. This article presents a new idea of using a noniterative method to compensate for the spatially variant PSF.

Ethical Foreground and Background in Adult Educator Work

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Adult educators work in a complex ethical environment. The very act of contributing to the learning of another is fraught with moral overtones. In this paper we consider the ethical dimensions of adult educator practice by distinguishing the ethical features of the context or ‘background’ of practice from the ethical capabilities and decision ...

Marie NDiaye : flou générique et réalisme magique [PDF]

open access: yesSvět Literatury
The notion of blur will be explored in a short story by Marie NDiaye, Autoportrait en vert, published by Mercure de France. Following the principle of the “Traits et portraits” collection, this book features self-portraits punctuated by illustrations ...
