В работе предложен метод прореживания видеопоследовательностей, основанный на оценивании сходства двух последовательных черно-белых кадров с применением знаковой корреляционной функции вида «знак-знак» и коэффициентов ассоциативности, проверке соответствия рассчитанных значений метрик предельным интервалам и принятии решений относительно удаления кадров. Рассмотрена обобщенная схема предложенного метода с подробным описанием этапов, описан алгоритм поиска сходства и различий между двумя последовательными черно-белыми кадрами видеопоследовательностей. Метод позволяет уменьшить размер видеопоследовательностей за счет удаления избыточных или повторяющихся кадров, тем самым сокращая объем хранимой информации и повышая эффективность обнаружения ключевых моментов на видеоизображениях, полученных в условиях неконтролируемой среды. Представлены результаты исследований, которые показали, что предложенный метод позволяет сократить избыточность кадров в два раза без потери важной информации и качества видеопоследовательностей.</p></abstract><trans-abstract xml:lang="en"><p>Video sequences redundant frame removal currently plays an important role in various video preprocessing applications related to video classification, change detection, and object recognition (e.g., defects, faults, human actions, etc.). This paper proposes a video sequence subsampling method based on estimating the similarity of two consecutive black-and white frames using a "sign-sign" correlation function and associativity coefficients, verifying the compliance of the calculated metric values with threshold intervals, and making decisions regarding frame removal. A generalized scheme of the proposed method is considered with a detailed description of the stages, and an algorithm for finding similarities and differences between two consecutive black-and-white frames of video sequences is described. This method reduces the size of video sequences by removing redundant or repeated frames, thereby reducing the amount of stored information and increasing the efficiency of detecting key moments in video images obtained in uncontrolled environments. Research results are presented, demonstrating that the proposed method can halve frame redundancy without losing important information or improving the quality of video sequences.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прореживание кадров</kwd><kwd>сходство кадров</kwd><kwd>видеопоследовательность</kwd><kwd>знаковая корреляционная функция вида «знак-знак»</kwd><kwd>коэффициенты ассоциативности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>frame subsampling</kwd><kwd>frame similarity</kwd><kwd>video sequence</kwd><kwd>sign-sign correlation function</kwd><kwd>associativity coefficients</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">Quality-guided key frames selection from video stream based on object detection / Chen Mingju, Xiaofeng Han, Hua Zhang [et al.] // Journal of Visual Communication and Image Representation. – 2019. – Vol. 65 (24). – Article no. 102678. – DOI 10.1016/j.jvcir.2019.102678.</mixed-citation><mixed-citation xml:lang="en">Quality-guided key frames selection from video stream based on object detection / Chen Mingju, Xiaofeng Han, Hua Zhang [et al.] // Journal of Visual Communication and Image Representation. – 2019. – Vol. 65 (24). – Article no. 102678. – DOI 10.1016/j.jvcir.2019.102678.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Best frame selection to enhance training step efficiency in video-based human action recognition / A.
