  • Apparatus and method for tracking the location of a pointing element in a cropped video field
    Patent number: 8665375
    Abstract: An apparatus for tracking a pointing device in use by a foreground subject in a sequence of video fields having a foreground component and a background component, where the pointing device is the leftmost or rightmost object within the foreground component. The apparatus determines the boundaries of a cropped video field within each of the video fields and determines a pixel value and scan line representing the leftmost and rightmost positions of the foreground subject and pointing device for that cropped video field. The apparatus determines the centerline of the foreground subject for each cropped video field, and using the centerline, determines whether the pointing device is on the right side of the cropped video field or the left side of the cropped video field. The position of the pointing device is stored after receipt of a signal generated by the foreground subject.
