Publication number: 20190342479Abstract: Systems and methods for analyzing scenes from cameras imaging an event, such as a sporting event broadcast, are provided. Systems and methods include detecting and tracking patterns and trails. This may be performed with intra-frame processing and without knowledge of camera parameters. A system for analyzing a scene may include an object characterizer, a foreground detector, an object tracker, a trail updater, and a video annotator. Systems and methods may provide information regarding centers and spans of activity based on object locations and trails, which may be used to control camera field of views such as a camera pose and zoom level. A magnification may be determined for images in a video sequence based on the size of an object in the images. Measurements may be determined from object trails in a video sequence based on an effective magnification of images in the video sequence.Type: ApplicationFiled: July 15, 2019Publication date: November 7, 2019Inventors: Smadar GEFEN, Gregory House, Yuecheng Zhang

Patent number: 9124856Abstract: Described herein are methods and systems for video event detection for contextual annotation and synchronization. Exemplary embodiments relate to a method comprising receiving a video stream, extracting a first event from the video stream, determining an index value identifying a location within the video stream corresponding to the first event, and inserting content based on the first event at a location identified by the index value. Further exemplary embodiments relate to a system comprising an event-based data extractor that receives a video stream and extracts a first event from the video stream, a processor that determines an index value identifying a location within the video stream corresponding to the first event, and a video insertion module inserts content based on the first event at a location identified by the index value.Type: GrantFiled: August 31, 2012Date of Patent: September 1, 2015Assignee: DISNEY ENTERPRISES, INC.Inventors: Nikhil Deshpande, Yuecheng Zhang

Patent number: 8922718Abstract: A method, apparatus, and computer program product are described that utilizes spatial modeling to represent foreground objects of an event to allow virtual graphics to be integrated into a background of the event in the presence of dynamic objects. The present invention detects a presence of dynamic objects within a region of interest from a video depicting the event. The present invention produces a suppression key corresponding to the dynamic object when present in the video or a suppression key with a default value when and where no dynamic object is present in the video.Type: GrantFiled: October 21, 2010Date of Patent: December 30, 2014Assignee: Disney Enterprises, Inc.Inventors: Gregory House, Ximin Gong, Cen Rao, Yuecheng Zhang
