20120099765 | METHOD AND SYSTEM OF VIDEO OBJECT TRACKING - Methods and systems are provided to determine a target tracking box that surrounds a moving target. The pixels that define an image within the target tracking box can be classified as background pixels, foreground pixels, and changing pixels which may include pixels of an articulation, such as a portion of the target that moves relatively to the target tracking box. Identification of background image pixels improves the signal-to-noise ratio of the image, which is defined as the ratio between the number of pixels belonging to the foreground to the number of changing pixels, and which is used to track the moving target. Accordingly, tracking of small and multiple moving targets becomes possible because of the increased signal-to-noise ratio. | 04-26-2012 |
20120027299 | METHOD AND SYSTEM FOR AUDIENCE DIGITAL MONITORING - Aspects of the present invention allow for real-time people monitoring method and system for estimation of the size and flow density of a given group of people located in a given area of space. The method and system may be used to monitor live or recorded camera input, foreground segmentation, human tracking, height estimation, and dwell estimation. In particular, human detection may be achieved using a spatio-temporal variance analysis calculation methodology for moving target detection. | 02-02-2012 |
20110170994 | TOWING ROBOT - A remotely controlled robot for towing a wheeled target vehicle includes a wheel lift assembly having a left side, a right side, and at least one wheel capture arm, at least one drive wheel provided toward each of the left and right sides of the wheel lift assembly, at least one drive motor for driving the drive wheels, and a lift actuating mechanism, wherein the wheel capture arm rotates from the wheel lift assembly to secure a wheel of the target vehicle, and wherein the secured wheel of the target vehicle is raised above a ground surface by the lift actuating mechanism. The lift actuating mechanism may be integrated with the wheel chassis to raise the wheel lift assembly via lift bars. The wheel lift assembly may include a truck assembly and an inclined rail supported on the truck assembly. | 07-14-2011 |
20100046797 | METHODS AND SYSTEMS FOR AUDIENCE MONITORING - Systems and methods for audience monitoring are provided that include receiving an input including a recording or live feed of an audience composed of several persons, detecting foreground of the input, performing blob segmentation of the input, and analyzing human presence on each segmented blob by identifying at least one person, identifying a spatial distribution of at least one identified person, determining a dwell time of at least one identified person, determining a temporal distribution of at least one identified person, and determining a gaze direction of at least one identified person. Such detecting provides the ability to track individual persons present in the audience, and how long they remain in the audience. The method also provides the ability to determine gaze direction of persons in the audience, and how long one or more persons are gazing in a particular direction. | 02-25-2010 |
