A Method for Assessing the Pupil Center Coordinates in Eyetracking with a Free Head Position

. IR-illuminated Eyetracking systems include cornea reflection and pupil center coordinates detection to calculate the ope rator’ s gaze fixation point. When you turn a view of a large angle, some of the frames are blurred, and the coordinates are unreliable. The article describes a method for determining the center of the pupil in the gaze fixation system for operation at an increased camera frame rate. Comparison with known algorithms is given. The algorithm execution average time is about 1.2 ms on a typical office computer by processing images in fragments of the order of 340x240 pixels. © 2021 Journal of Biomedical Photonics & Engineering.
