取以及目标的跟踪四个方面-Extraction and tracking of moving targets is a visual analysis, to understand high-level acts, as well as encoding movement in computer vision applications, such as basic and important step, but also in computer vision problems. In this paper, the movement in-depth study of the accuracy of visual target extraction and tracking algorithms, including motion detection, the shadow of the elimination of external contour extraction and tracking of targets in four areas
