摘要: Systems and methods for analyzing scenes from cameras imaging an event, such as a sporting event broadcast, are provided. include detecting tracking patterns trails. This may be performed with intra-frame processing without knowledge of camera parameters. A system scene object characterizer, foreground detector, tracker, trail updater, video annotator. provide information regarding centers spans activity based on locations trails, which used to control field views pose zoom level. magnification determined images in sequence the size images. Measurements trails effective sequence.
