Publication number: 20120327246Abstract: A system for automatically acquiring high-resolution images by steering a pan-tilt-zoom camera at targets detected in a fixed camera view is provided. The system uses automatic or manual calibration between multiple cameras. Using automatic calibration, the homography between the cameras in a home position is estimated together with the effects of pan and tilt controls and the expected height of a person in the image. These calibrations are chained together to steer a slave camera. The manual calibration scheme steers a camera to the desired region of interest and calculates the pan, tile and zoom parameters accordingly.Type: ApplicationFiled: September 4, 2012Publication date: December 27, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Andrew William Senior, Sharathchandra Pankanti, Arun Hampapur, Lisa Marie Brown, Ying-Li Tian

Patent number: 8284249Abstract: A method for real time processing of a sequence of video frames. The video frames are received in synchronization with a recording of the video frames in real time for triggering an alert. The method is implemented by execution of program code on a processor of a computer system. Each frame includes a two-dimensional array of pixels and a frame-dependent color intensity at each pixel. An algorithm determines whether a static object in a current frame of the video frames is an abandoned object or a removed object. The determined status, the current frame time, the static region, and the static object are stored in a data storage medium of the computer system. An alarm is triggered in response to satisfaction of requirements that include a persistence requirement, a non-persistence duration requirement, and a persistence duration requirement.Type: GrantFiled: March 25, 2008Date of Patent: October 9, 2012Assignee: International Business Machines CorporationInventors: Rogerio Schmidt Feris, Arun Hampapur, Zuoxuan Max Lu, Ying-li Tian
