Patents by Inventor William Severson

William Severson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8564661
    Abstract: A video surveillance system is set up, calibrated, tasked, and operated. The system extracts video primitives and extracts event occurrences from the video primitives using event discriminators. The extracted video primitives and event occurrences may be used to create and define additional video analytic rules. The system can undertake a response, such as an alarm, based on extracted event occurrences.
    Type: Grant

    Date of Patent: October 22, 2013
    Assignee: ObjectVideo, Inc.
    Inventors: Alan J. Lipton, John I. W. Clark, Zhong Zhang, Peter L. Venetianer, Thomas Strat, Mark Allmen, William Severson, Niels Haering, Andrew Chosak, Matthew Frazier, James Sfekas, Tasuki Hirata
  • Publication number: 20080095435
    Abstract: A method for segmenting video data into foreground and background portions utilizes statistical modeling of the pixels. A statistical model of the background is built for each pixel, and each pixel in an incoming video frame is compared with the background statistical model for that pixel. Pixels are determined to be foreground or background based on the comparisons. The method for segmenting video data may be further incorporated into a method for implementing an intelligent video surveillance system.

  • Patent number: 6738424
    Abstract: A method of generating and utilizing a scene model from a sequence of video frames produces a three-dimensional scene model, useful for video processing. The method separates foreground and background data. It uses an estimate of relative motion of an observer to project each frame onto a coordinate system of the three-dimensional scene model. It then merges the background data of a given frame into the scene model.
