The aim of this work is the software implementation of three image scaling algorithms using parallel computations, and the development of an application with a graphical user interface for the Windows operating system to demonstrate the operation of algorithms and to study the relationship between system performance, algorithm execution time and the degree of parallelization of computations. 48 Three methods of interpolation were studied, formalized and adapted to scale images. The result of the work is a program for scaling images by different methods. The paper also presents a comparison of the quality of scaling by different methods.

This publication offers an annotated translation of Jacques Goar’s notes on the epiclesis from his Euchologion (1647). The translation is accompanied by an introduction that places Goar’s text within the historical and polemical context of Greco-Latin controversies on the moment of consecration, particularly the epiclesis debate at the Council of Florence (1439). Goar’s interpretation, rooted ...

This article investigates the problem of approximating the generalized
Erdélyi-Kober fractional operator (often referred to as the Lowndes operator)
using cubic splines. A method based on cubic spline interpolation
is proposed for approximating the operator on a non-uniform grid. The
convergence rate of the proposed method is proven, and its stability is
analyzed. Error bounds are established for functions in ...

Statistical evaluation of three-dimensional auto- and cross-correlation functions for increments from the first guess was performed to interpolate the complex forecast (postprocessing) of geopotential height and temperature to regular grid points. The forecast fields from the ICON model were used as the first guess. Positive definiteness was provided in the evaluation. The verification of the ...

Digital steganography protects the privacy of data by hiding them in some digital containers, such as images. Protection of confidential messages by hiding them in digital images faces the problem of balancing the main performance indicators, i.e. embedding imperceptibility and capacity. Metaheuristic optimization can be used to flexibly customize embedding options, including parameters and locations ...

Применение цифровых водяных знаков (ЦВЗ) является перспективным средством защиты авторских прав на цифровой контент. В этом исследовании предлагается новый алгоритм невидимого встраивания ЦВЗ в гибридную пространственно-частотную область изображений с применением метаэвристической оптимизации, который отличается устойчивостью к различным атакам обработки изображений, включая JPEG-сжатие. ...

The widespread use of digital content makes the task of protecting author’s and owner’s rights increasingly important, in particular with regard to digital images. Digital watermarking technology is an effective tool that solves many problems associated with proving authorship of images, verifying authenticity, and tracking illegal copying. An effective watermarking algorithm requires achieving high levels ...

Highly skilled cross-country skiers often prefer the double poling technique due to its speed and versatility. This work is aimed at developing a biomechanical model of a skier using the double poling technique. To do this, using video recordings of the competition, experimental data of eight elite-level athletes (four male and four female) were prepared ...
