“…The proposed approach uses the fast radial symmetry transform as the basis for detecting the pupil center. The FRST was also used in the algorithm presented by Skodras et al [15] for remote eye tracking systems. Our contribution was directed at validating the use of the symmetry transform in head-mounted, gray-scale, high-resolution images.…”

“…In recent years, several gaze and head tracking methods have been proposed [30], [31]. As one of the most popular open-source facial analysis tools, OpenFace is utilized for the purpose of extracting the features of the driver's gaze and head due to its fine performance and robustness.…”

“…To this end, an algorithm for accurate eye center localization in low resolution images based on our previous work [46,47] is used. In order to robustly and accurately detect eye centers, the system builds upon a synergy of chrominance information and radial symmetry.…”
