WAYS TO REDUCE THE LABOR INTENSITY OF WORK, SIMPLIFY THE DEVELOPMENT PROCESS AND IMPROVE THE QUALITY OF THE IMAGE WHEN DESIGNING A TYPOGRAPHIC PORTRAIT IN VECTOR AND RASTER GRAPHICS EDITORS

The paper proposes new ways to reduce the labor intensity of work, simplify the development process and improve the quality of the image when designing a typographic portrait from a photo in the editors of raster graphics Adobe Photoshop and vector graphics Adobe Illustrator or Corel Draw. To reduce the labor intensity of work and simplify the process of developing a typographic portrait from a photo in a raster graphics editor, it is proposed to pre-process the photo in Adobe Photoshop with the “Pasteurization” command to select several color levels of the image, along the contours of which you can then draw lines that form a path for writing the letters from which the typographic portrait is formed. To simplify the process of developing a typographic portrait and improve the quality of the image in the vector graphics editors Adobe Illustrator or Corel Draw, it is suggested, after processing the photo in Adobe Photoshop with the “Pasteurize” command to select several levels of the image, upload the converted photo to the vector editor Adobe Illustrator/Corel Draw, and circle each color level with the “Pen” tool to form closed vector paths, which are then filled with letters, Having previously converted them into curves for the possibility of transformation along the inner boundaries of closed vector contours, at the same time, the letters that fill this or that contour are given the color of this contour.

Three-Dimensional Modeling of Firearm Injuries in Forensic Medicine

Introduction. Forensic medical investigations, including illustration, evidence collection, and expert conclusion preparation, have faced significant challenges in recent years. One of the primary challenges for Ukraine’s forensic medical service today is the examination of firearm-related injuries, necessitating substantial improvements to traditional methodologies. The study aimed to develop a methodology for the three-dimensional spatial reconstruction of firearm injuries. Methods. An automatic pistol CZ83 of medium caliber, manufactured in the Czech Republic and chambered for 7.65x17 mm ammunition, was used in the study. Roma Plastilina No. 1 ballistic gelatin, produced in the USA, served as the target and reproducing material for controlled ballistics tests. The experiments included 15 shots, during which the main morphological elements of skin injury, the subcutaneous adipose tissue, and the wound channel at the entry, middle, and exit points were studied. These were photographed, analyzed using photogrammetry, and converted into a three-dimensional format with the graphic editors Agisoft PhotoScan and 3Ds Max. Results. Measurements of all parameters obtained through classical methods differed significantly (p<0.05) from those obtained using 3D modeling. However, Cohen’s d values indicated that the differences were very small for defect size measurements, small for the abrasion ring and wound channel diameter across all sections, and medium for the entry wound diameter. Conclusions. The developed methodology for three-dimensional modeling allows for the accurate recording of the main morphometric parameters of firearm injuries, making it a viable alternative to traditional measurement methods.

ACCELERATING IMAGE PROCESSING USING PARALLEL COMPUTATIONS IN OPENMP: DEVELOPMENT AND PERFORMANCE ANALYSIS OF A GRAPHICS EDITOR

In today’s digital world, image processing plays a crucial role in various aspects of human life. From creating visual content for social media to analyzing medical images, powerful tools for image manipulation are in constant demand. The growing requirements for image quality and processing speed make the search for efficient methods to accelerate these processes highly relevant. This paper investigates the development and implementation of a graphics editor that utilizes OpenMP parallel computing to accelerate data processing. This technology enables the efficient distribution of computational tasks across multiple processor cores, significantly improving system performance. The developed software offers a set of popular graphic effects, including negative, grayscale, sepia, blur, sharpening, and posterization. Each effect is implemented in both sequential and parallel modes using OpenMP, allowing for the comparison of different computational approaches. To evaluate the effectiveness of the proposed solution, a series of experiments were conducted on images of various sizes. These experiments involved applying each effect to images ranging from small icons to high-quality photographs. A comparative analysis of the efficiency of sequential and parallel computation methods demonstrated the significant advantages of the latter. The results of the study show a substantial acceleration of image processing when using OpenMP technology. This acceleration is particularly noticeable for computationally intensive effects such as blurring or sharpening, and when working with large images. In some cases, it was possible to achieve a significant increase in processing speed, opening up new possibilities for working with large volumes of graphic data. This research has significant practical value for software developers working on optimizing the performance of graphics editors and other image processing applications. It demonstrates how the application of modern parallel computing technologies can significantly improve the efficiency of working with graphic data, paving the way for the creation of more powerful and faster image processing tools.

On the issue of reliability of power transmission (on the example of the branch of PJSC Rosseti Volga – Penzaenergo)

The article is a continuation of a series of publications focusing on the analytical assessment of specifics of power transmission in various structural divisions of PJSC Rosseti and is dedicated to the consideration of specific features of electric energy transport in the PJSC Rosseti Volga – Penzaenergo branch electric networks over the period of 2018 – 2023. The characteristic of the structural and balance state of the company's electrical networks for the period under study is presented. Based on the data published in the open press, the analysis of the number of emergency shutdowns and their consequences in electric networks of all levels of rated voltage was carried out. In accordance with the accepted classification, the intensity of these outages was analyzed depending on the amount of electrical energy undersupplied to consumers. The percentage ratio of the value of electrical energy not delivered as a result of emergency shutdowns is analyzed according to the accepted criteria of the intensity level of these failures. It was found that the smallest number of failures of extreme intensity accounts for more than 25% of undelivered electrical energy. The percentage ratio of the amount of electricity not delivered as a result of emergency outages is compared with losses of electricity as a result of unauthorized connections. Specific groups of causes of emergency shutdowns have been identified and the percentage ratio of the number of failures due to these causes to the total number of failures during the period under study has been determined. General scientific methods and methods of numerical analysis were used in the study. The technologies of Excel, Paint 3D software shells, MATLAB graphics editor, as well as author's software solutions were used as a tool base. The results obtained may be of interest to the management of the power grid structures of the Russian Federation, as well as to engineers and researchers engaged in research in the field of improving the reliability of power supply to consumers.

Cartographic animations, a supporting technology for education

Abstract. To date, basic theoretical and methodological ideas of animated cartography have been formed, as well as general schemes for animated maps compilation. However, the technological issue remains relevant in this domain due to the abundance of modern tools that can be used for compilation of animated maps. Particularly, most of currently implemented cartographic animation methodologies require the use of a variety of specialized software, including geographic information systems (GISs), vector and raster graphical editors, video effects editing software, and others. So the data processing and conversion techniques are extremely complicated in some cased, when data converted from one software platform to another.In our study, we established investigation of popular desktop GISs functionality application as a full-cycle animated cartography environment. In such a context, we discover approaches to improve methodology of animated maps automated compilation. To prototype a full-cycle animation in GIS environment, we developed a set of animation algorithms implemented in QGIS and documented the algorithms using UML (Unified Modeling Language) diagrams.

Standardization of color measurement in the medical photography in clinical practice

BACKGROUND: For many medical specialties, photography is a routine element of work. Environmental factors equally and significantly influence the interpretation of colour light perception and the quality of photographic recording. Standardization of conditions in medical photography is necessary for subsequent quantitative assessment of the postoperative skin scar by analysing colour coordinates in the RGB system. AIM: To determine the impact of illumination and shooting distance at colour coordinates when studying unaltered skin. METHODS: Five volunteers without any skin diseases and no make-up on their facial skin were taken in the study. Skin type by the Fitzpatrick scale was II–III. Digital photography was made with a mobile device camera at distance 30 cm from the subject. For each participant, a series of digital photographs was taken at a distance of 20, 30, 40, 50, 60, 70 cm from the light source. Colour coordinates in the RGB system were measured in the digital graphics editor Adobe Photoshop CS6. Statistical analysis of the obtained data was carried out using Microsoft Office Excel 2019, Phyton 3.11. RESULTS: The analysis of variance by the ANOVA method was used as a statistical analysis. In order to determine a statistically significant difference between the sets, Tukey HSD test was performed. A total of 1764 coordinates of three colours were subjected to statistical analysis (R=588, G=588, B=588). When constructing a heat map of the cross-correlation of the absolute values of each colour at each distance, taking into account the type of light source among themselves, the data had a strong direct correlation, regardless of the study area. When constructing a linear graph, coordinates of any of the zones were located on the same straight line. CONCLUSION: Photography conditions were experimentally determined under which the color interpretation of light is constant. Results of the study should be taken into account during medical photography and subsequent color assessment of postoperative skin scars.

Analytical and geometric interpretation of the flat arrangement of points by means of metric geometry in the study of metric spaces

Abstract When studying metric spaces, students of higher education often have difficulties with understanding the basic concepts and properties of these spaces. This, to a large extent, is a consequence of the significant level of formalization of such concepts on the one hand, and the preservation of the corresponding formulations and names familiar to students from a school mathematics course. To overcome these difficulties, it is advisable to use methods of geometric interpretation and visualization of these properties. At the same time, it is appropriate to use elements of metric geometry. Its methods make it possible to interpret the geometric features of the mutual placement of points of metric space in Cartesian (rectangular) coordinate systems, which are familiar to students of higher education. Moreover, it becomes possible to visualize these features with the help of graphic editors, since they, as a rule, use numerical values of the coordinates of points to visualize them. Based on the definition of an angle as an ordered trio of points of an arbitrary metric space, and the angular characteristic of this angle, the fact of the flat placement of four points of a non-Euclidean metric space is established, and examples of digital visualization of this arrangement using the dynamic geometric environment GeoGebra 3D are given.
