  • Fiducial designs and pose estimation for augmented reality
    Patent number: 7565004
    Abstract: Novel fiducial designs that are based on a plane circle are Disclosed. These fiducial designs can provide five or six degree of freedom poses with a single fiducial using efficient closed form solutions. A novel pose estimation method is used to select the appropriate solution from the multiple solutions obtained, given certain application assumptions, is also disclosed.

  • Region segmentation and characterization systems and methods for augmented reality
    Patent number: 7515756
    Abstract: A novel method of region segmentation for an image is disclosed. Specifically, region segmentation is accomplished by dividing the image into a plurality of sticks of pixels and determining whether each stick belongs to any region from a set of region. Each stick that belongs to any region is classified as belonging to a specific region.
