Статья посвящена определению системных колориметрических параметров демаскировки крыс (Rattus norvegicus) при видеорегистрации в городских условиях. Найдена комбинация значений колориметрических параметров, которая может сыграть роль системного колориметрического параметра, являющейся наиболее выраженной мерой пестроты защитной окраски Rattus norvegicus. Эффективность использования найденного системного колориметрического параметра была проверена обработкой полученного изображения крысы на фоне фрагмента городского пейзажа. Полученные результаты обработки изображения крысы показывают эффективность повышения контрастности силуэта животного, что увеличивает эффективность видео-регистрации численности и миграций серой крысы в условиях города.
The relevance of the article is determined by threats to biobesopathy in urban conditions, which can be created by loss of control over the population of rats (Rattus norvegicus). The purpose of the study is to determine of the system colorimetric parameters of unmasking rats with video recording in urban conditions. This goal is achieved by mathematical modeling of systemic colorimetric parameters of the rat’s protective coloration. Exceeding these values over similar background values of the urban landscape fragments allows unmasking animals. Modeling is performed using new class of models – discrete models of dynamic systems, based on the actual image material Rattus norvegicus. Images taken from the Internet and processed using MatLab package. A values combination of the colorimetric parameters are found that can play the role of the system colorimetric parameters, which is the most pronounced measure of the variegation of the Rattus norvegicus protective coloration. This value is entered in a specially created database, which contains information about the spatial coordinates of this segment in the image. The value of the specified color parameter for each segment during image processing is denoted by a conventional color. Placing a segment on an image is determined by its spatial coordinates entered in the database. The effectiveness of SCP using was verified by image processing of the rat against the background of a fragment of the urban landscape. The results of image processing of the rat show the effectiveness of contrast increasing of the silhouette of the animal, which increases the efficiency of video recording of numbers and migrations of the gray rats in urban conditions.
