TECHNIKI ROZPOZNAWANIA TWARZY

The problem of face recognition is discussed. The main methods of recognition are considered. The calibrated stereo pair for the face and calculating the depth map by the correlation algorithm are used. As a result, a 3D mask of the face is obtained. Using three anthropomorphic points, then constructed a coordinate system that ensures a possibility of superposition of the tested mask.Omawiany jest problem rozpoznawania twarzy. Rozważane są główne metody rozpoznawania. Użyta zostaje skalibrowana para stereo dla twarzy oraz obliczanie mapy głębokości poprzez algorytm korelacji. W wyniku takiego, uzyskiwana jest maska twarzy w wymiarze 3D. Użycie trzech antropomorficznych punktów, a następnie skonstruowany systemu współrzędnych zapewnia możliwość nakładania się przetestowanej maski

Сжатие графической информации с использованием тематических текстур

To decorate surface of terrain thematic textures are used. It is supposed that observer is not often interested in the exact photographic information about the wide areas covered, for instance, by forest, water, etc., so that the benefits of photographic texture can be obtained by composing a number of patterns called "themes" to produce a final texture of the specific area. The goal of using thematic textures is to abolish the need of the global area texture, and additionally, animation features become available by simple means

Assessment of the Epidemiological Effectiveness of the Temporary Transfer of Schoolchildren to Distance Learning during the Spread of COVID‑19 by the Example of the Saratov Region

Temporary closure of schools is an effective anti-epidemic measure during periods of rising incidence of acute respiratory viral infections and influenza, which is confirmed by the results of a large number of scientific works. In particular, the effectiveness of this measure consists in reducing the incidence among students. In the context of the spread of COVID‑19 in the Russian Federation, like in many other countries, the temporary transfer of schoolchildren to distance learning has also been repeatedly introduced; however, it remains unclear whether the measure under consideration is effective in relation to the new coronavirus infection.The aim of the study was to assess the epidemiological effectiveness of the temporary transfer of students to distance learning during the spread of COVID‑19 in the Saratov Region.Materials and methods. The analysis was carried out on the basis of statistical data of the Rospotrebnadzor Administration in the Saratov Region on the incidence of COVID‑19 for the period of 2020–2022, as well as materials from published scientific papers.Results and discussion. Analysis of the data on the school closure in 2020 has revealed a decrease in the incidence among schoolchildren (–42.9 %) and an increase in the incidence among people aged 65 years and older (+7.2 %); in 2021, there was a decrease in the incidence among schoolchildren (–15.6 %) and an increase in the indicator value as regards the elderly (+17.8 %); in 2022, another school closure led to an increase in the incidence of COVID‑19 among schoolchildren (+7.8 %) and people over 65 years old (+44.2 %). Based on the results obtained, one can conclude that the measure under consideration is inexpedient due to the fact that the most vulnerable category of the population (persons aged 65 years and older) is actively involved in the epidemic process, which in turn leads to a significant deterioration of the epidemic situation

Класифікація методів антиаліайзингу

У роботі проведено аналіз існуючих методів антиаліайзингу зображень і запрпопоновано їх класифікаціюThe purpose of this paper is to analyze the existing methods Anti-Aliasing and try the most common classification methods, including methods of Super-Sampling, Multy-Sempling and post-processing methods, which also relate to methods Anti-Aliasing. The basic principle of Anti-Aliasing - a " make low-contrast " sharp boundaries between colors in order to achieve the visual effect of a smooth transition between tones. Different requirements for tools Anti-Aliasing based on tasks performed by computer systems encourage manufacturers to develop graphical tools with different specifications and characteristics for maximum satisfaction of needs subject area. This creates a need to develop classification methods Anti-Aliasing to determine the optimal method and its adaptation to the tasks used

Methodological Approaches to Assessing the Economic Damage Associated with the Incidence of Hemorrhagic Fever with Renal Syndrome in the Russian Federation

The aim of the study was to develop methodological approaches to assessing the economic damage associated with the incidence of hemorrhagic fever with renal syndrome (HFRS) and to calculate the economic damage by the example of an outbreak of HFRS in the Saratov region in 2019. Materials and methods. The paper analyzes the economic indicators of the Federal State Statistics Service; data on the incidence of HFRS in the Russian Federation for the period of 2019–2022. To calculate the cost of outpatient and inpatient medical care, as well as the costs associated with the medical follow-up of convalescents, the indicators of the Program of state guarantees of free provision of medical care to citizens for 2022 and for the scheduled period of 2023 and 2024 were used. The calculation of economic losses associated with the payment of temporary disability benefits was carried out according to the equation provided in the Federal Law No. 255-FZ dated December 29, 2006 (as amended on October 07, 2022). Economic losses associated with premature death at an economically active age were calculated based on the value of unproduced GDP due to lost years of life in the corresponding age group. Results and discussion. The costs of treatment, rehabilitation and payment of temporary disability benefits for 1 case of HFRS at the age of 0 to 56.5 years for the female population and from 0 to 61.5 years for the male population amount to 140 495 rubles; over the age of 56.5 years for the female population and 61.5 years for the male population – 95 412 rubles, respectively. Each fatal case of HFRS aged 0 to 16 years among the male population costs the state 38 976 231 rubles; among the female population – 34 708 331 rubles; in active working age – the value of economic damage varies depending on the age of the person who died of HFRS. The economic damage of the outbreak of HFRS in the Saratov Region (2019), taking into account the direct expenditures of the healthcare system and indirect losses of the country’s economy amounted to 441 453 432 rubles. It is of note that the structure of the main damage is dominated by indirect losses in the economy caused by the premature death of people in economically active age
