In this paper, the main attention is focused on the stage of image segmentation and on the choice of a quality indicator for the evaluation of image segmentation. In general form the segmentation problem of color and tone images is formulated in. The main approaches that are used in methods and techniques of image segmentation are highlighted. The need to evaluate the results of the work of methods and techniques of image segmentation to assess their performance has been established. The options for the image segmentation quality assessing of both at the objective (quantitative) level and at the subjective (qualitative) level are considered. The main features of qualitative segmentation are highlighted. Two main groups of indicators for evaluating the quality of segmentation were analyzed: indicators based on comparison with the reference result of image segmentation and the indicators for which benchmark segmentation is not required. Their main disadvantages when used in evaluating the results of image segmentation are described. The information quality indicator – Kullback-Leibner divergence for the image segmentation quality assessing of the results of image segmentation is considered. The result of image segmentation by the Canny edge detector is presented. The estimation of the quality of the segmented image was calculated using the information Kullback-Leibner divergence for pairs of images of different scales. The paper shows show a graph of the dependence of the value of the Kullback-Leibler divergence on the value of the scale factor of the original image. Keywords— Canny edge detector, image segmentation, objective criteria, Kullback-Leibler divergence, quality indicator.

A scheme of interrelationships of external and internal macro- and microenvironmental factors and their influence on the states of the unmanned aerial vehicle system has been developed. It is proposed to use an approach with elements of graph theory and set theory to analyze the states of an unmanned aircraft complex. The given graph of the functioning of the man-machine system of a sample of the unmanned aircraft complex of the “micro UAS unmanned aircraft system” class sets the transitions that determine the closed cycle of the execution of a combat mission. An example of building a structure of functional indicators of unmanned aerial vehicles with life cycle elements using graph theory for the analysis of “bottlenecks” in ensuring reliability is given. The analysis of “bottlenecks” in the control systems of unmanned aerial vehicles in the area of the ground control station – unmanned aerial vehicle is aimed at determining directions for increasing reliability, flight safety, increasing functionality, flight range and improving ergonomic characteristics. A comprehensive analysis of the functioning and dynamics of changes in reliability indicators with relevant data for previous periods of operation will allow us to draw specific conclusions about the actual level of reliability of the UAS un manned aircraft system fleet and identify bottlenecks for further improvement and the possibility of transitioning to the use of third-generation BpAK (autonomous devices) with self-learning systems with artificial intelligence. The theoretical rationale and the given practical recommendations should be taken into account when developing new prospective models of unmanned aerial vehicles for the Armed Forces of Ukraine in accordance with their official purpose.

At the present stage of development of unmanned aircraft systems work continues at a rapid pace to further improve their capabilities in the direction of more effective combat and special tasks. This is especially noticeable in two key areas: increasing the range and flight duration; reducing the physical size of the unmanned aerial vehicles. The combination of increasing flight duration and decreasing design characteristics significantly affects the requirements for unmanned aircraft system communication equipment and the development of a beyond line of sight satellite communication channel, which is currently considered as the main channel for transmitting intelligence, telemetry information in real time. Under existent warfighting conditions, the development of communication lines on the principle of a beyond line of sight with the use of ground or airborne relay stations, or through the introduction of additional ground control stations is virtually unjustified, due to the high dynamics of operational conditions and time constraints for decision making. In this context, the unmanned aerial vehicles' satellite communication channels are subject to strict requirements to ensure the combat missions are carried out successfully and safely. The article examines current approaches to the implementation of satellite communication channels with unmanned aerial vehicles in the context of the requirements for both on–board equipment and directly to the development of a satellite communication channel. Recommendations are given for the basic requirements for the organization of satellite duplex communication beyond line–of–sight with unmanned aerial vehicles based on geostationary (medium-altitude) high throughput satellites in the Ka frequency range.
