  • User recognition and gaze tracking in a video system
    Patent number: 11163995
    Abstract: Some embodiments include a computer-implemented method for tracking a gaze of a user that can include receiving image data that includes a plurality of eye landmarks that identify a perimeter of a user's eye, applying dynamic thresholding to the image data, determining a convex hull based on the dynamically thresholded and image data, computing and fitting an ellipse along a boundary of the convex hull, the ellipse corresponding to an iris of the user's eye, updating the image data with the computed ellipse, computing a refined ellipse by reapplying the dynamic thresholding and determining the convex hull using the updated image data, and determining a gaze direction of the user based in part on a position of the refined ellipse relative to the perimeter of the user's eye.
