Рассмотрена задача оптимизации распределения плотности пикселов по зоне обзора, обеспечивающая минимум избыточности видеоизображений при ограниченном пространстве мест установки камер. Представлено решение устранения избыточности информативности видеосигналов, приводящей к чрезмерным затратам ресурсов по передаче, хранению, обработке и отображению видеосигналов. Метод. Предлагаемый подход основан на интегральной оценке непрерывного распределения плотности пикселов в зоне обзора по сравнению с необходимым значением для решения заданной задачи наблюдения. Формализована задача наблюдения — определение пространств наблюдения и возможных мест установки камер. Показана методика расчета распределения плотности пикселов по зоне обзора с последующей оптимизацией параметров установки по критериям минимума значения коэффициента избыточности при достижении требуемого значения плотности пикселов или максимума минимальной плотности пикселов при заданном ограничении на коэффициент избыточности. Основные результаты. Предложены интегральный коэффициент и критерии оптимизации избыточности, учитывающие характер распределения плотности пикселов и метод оптимизации, позволяющий максимизировать минимальное значение плотности пикселов или минимизировать значение избыточности видеоизображения. Показано, что использование нормировки как по минимально требуемой плотности пикселов, так и по протяженности зоны обзора, позволяет использовать предложенные критерии для большинства практических задач обнаружения и идентификации при разных параметрах установки камер. Приведен практический пример использования метода. Обсуждение. Представленные критерии и метод позволяют повысить эффективность системы видеонаблюдения за счет сокращения избыточности ресурсов при сохранении требуемой информативности. Результаты работы применимы к задачам видеоконтроля зоны одной или несколькими камерами, а также для решения разных задач наблюдения в одной зоне. Могут использоваться при разработке систем наблюдения и программ автоматизированного проектирования таких систем.</p></abstract><trans-abstract xml:lang="en"><p>The problem of optimizing the distribution of pixel density over the viewing area is considered, which ensures a minimum of redundancy of video images with a limited space for camera installations. A solution is presented to eliminate the redundancy of the informativeness of video signals, which leads to excessive resource costs for transmitting, storing, processing and displaying video signals. The proposed approach is based on an integral assessment of the continuous distribution of pixel density over the viewing area in comparison with the required value for solving a given observation task. The surveillance task is formalized — the definition of surveillance spaces and possible camera installation locations. A method for calculating the pixel density distribution over the viewing area is shown followed by optimizing the installation parameters according to the criteria of the minimum value of the redundancy coefficient when the required pixel density is reached or the maximum minimum pixel density with a given limitation on the redundancy coefficient. An integral coefficient and redundancy optimization criteria are proposed, taking into account the nature of the pixel density distribution and an optimization method that allows maximizing the minimum pixel density or minimizing the redundancy value of the video image. It is shown that the use of normalization in terms of both the minimum required pixel density and the length of the viewing area makes it possible to use the proposed criteria for most practical detection and identification tasks with different camera installation parameters. A practical example of using the method is given. The proposed criteria and method make it possible to increase the efficiency of the video surveillance system by reducing resource redundancy while maintaining the required information content. The results of the work are applicable to the tasks of video monitoring of a zone with one or more cameras as well as for solving various surveillance tasks in one zone. They can be used in the development of surveillance systems and computer-aided design programs for such systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>распределение плотности пикселов</kwd><kwd>плотность пикселов</kwd><kwd>информативность видеоизображений</kwd><kwd>избыточность информативности видеоизображений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pixel density distribution</kwd><kwd>pixel density</kwd><kwd>informativeness of video images</kwd><kwd>redundancy of video images informativeness</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Петраков А.В., Лагутин В.С.
