1. A computer-implemented method comprising:

  • identifying, by a processor, an initial pupil location of a pupil of an eye within a set of images of a video stream;

    identifying, by the processor, a first distance from a first corner of the eye to a first point on an outer edge of an iris of the eye located closest to the first corner and a second distance from a second corner of the eye to a second point on the outer edge of the iris located closest to the second corner;

    determining a total distance extending from the first corner of the eye to the second corner of the eye;

    determining, by the processor, an initial iris radius based on the first distance, the second distance, and the total distance; and

    determining, by the processor, a final pupil location and a final iris radius based on the initial pupil location and the initial iris radius.
