Abstract

The embodiment of the invention provides a moving target video tracking method and system. The method includes; dividing the to-be-tracked video into at least two sub-videos based on the convergence entropy, updating the different sub-videos to obtain different classifiers, then initializing a target position in a first frame of image of each sub-video by utilizing the classifier corresponding toeach sub-video, and finally tracking targets in other frames of images except the first frame of image in each sub-video by utilizing a target tracking algorithm. According to the method and the system, the to-be-tracked video is effectively divided on the basis of the convergence entropy, so that the long-time video is divided into the short-time video, the accuracy of video tracking is improved,and the situation of tracking failure can be effectively avoided; Meanwhile, different classifiers are obtained by updating different sub-videos, so that the classifier corresponding to each sub-video can adapt to the appearance change of the target in the tracking process of the moving target, the shielding problem can be effectively solved, and the accuracy of a target tracking result can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of target tracking, and more specifically, to a method and system for video tracking of a moving target. Background technique [0002] Object tracking is a research hotspot in the field of computer vision. With the popularization of video cameras, video tracking has broad application prospects, and has important applications in human-computer interaction, intelligent monitoring, and object recognition. [0003] In recent years, a large number of tracking algorithms have emerged. The existing tracking algorithms generally use a single classifier to separate the target from the background during the entire tracking process. However, in the video tracking process of moving targets, it is easy to appear the target Problems such as deformation and target occlusion lead to changes in the appearance of moving targets. Therefore, it is difficult to accurately separate the moving target from the...
