Patent number: 9355308Abstract: Video analytics data is audited through review of selective subsets of visual images from a visual image stream as a function of a temporal relationship of the images to a triggering alert event. The subset comprehends an image contemporaneous with the triggering alert event and one or more other images occurring before or after the contemporaneous image. The generated subset may be presented for review to determine whether the triggering alert event is a true or false alert, or whether additional data from the visual image stream is required to make such a determination. If determined from the presented visual essence that the additional data is required to make the true or false determination, then additional data is presented from the visual image stream for review.Type: GrantFiled: October 17, 2014Date of Patent: May 31, 2016Assignee: GlobalFoundries, Inc.Inventors: Quanfu Fan, Zuoxuan Lu, Sachiko Miyazawa, Sharathchandra U.

Patent number: 8934670Abstract: A method and system for real time processing of a sequence of video frames. A current frame in the sequence and at least one frame in the sequence occurring prior to the current frame is analyzed. Each frame includes a two-dimensional array of pixels. The sequence of video frames is received in synchronization with a recording of the video frames in real time. The analyzing includes performing a background subtraction on the at least one frame, which determines a background image and a static region mask associated with a static region consisting of a contiguous distribution of pixels in the current frame. The static region mask identifies each pixel in the static region upon the static region mask being superimposed on the current frame. The background image includes the array of pixels and a background model of the at least one frame and does not include any moving object.Type: GrantFiled: August 29, 2012Date of Patent: January 13, 2015Assignee: International Business Machines CorporationInventors: Rogerio Schmidt Feris, Arun Hampapur, Zuoxuan Lu, Ying-li Tian

Patent number: 8744123Abstract: A foreground object blob having a bounding box detected in frame image data is classified by a finite state machine as a background, moving foreground, or temporally static object, namely as the temporally static object when the detected bounding box is distinguished from a background model of a scene image of the video data input and remains static in the scene image for a threshold period. The bounding box is tracked through matching masks in subsequent frame data of the video data input, and the object sub-classified within a visible sub-state, an occluded sub-state, or another sub-state that is not visible and not occluded as a function of a static value ratio. The ratio is a number of pixels determined to be static by tracking in a foreground region of the background model corresponding to the tracked object bounding box over a total number of pixels of the foreground region.Type: GrantFiled: August 29, 2011Date of Patent: June 3, 2014Assignee: International Business Machines CorporationInventors: Russell P.
