“…Its main purpose is to track and locate the moving target of each frame of image in a video sequence and obtain the information of the target's position, moving direction, speed, size, etc., which is the basis for the next higher-level analysis of the target object [6]. Video tracking technology involves many disciplines, such as computer science, mathematics, physics, optics, and morphology, and it integrates many technologies, such as image processing, video feature extraction, pattern recognition and artificial intelligence, information analysis, detection, and recognition and tracking of target motion information, and has important significance and application prospect in both civil and military aspects [7]. Human detection and tracking technology, which can automatically identify and track dancers' targets, have always been a hot research direction in the field of computer vision [8].…”
