Pupil Center Detection Approaches: A Comparative Analysis [PDF]
Computación y Sistemas, 2021 In the last decade, the development of technologies and tools for eye tracking has been a constantly growing area. Detecting the center of the pupil, using image processing techniques, has been an essential step in this process. A large number of techniques have been proposed for pupil center detection using both traditional image processing and ...

Labelled pupils in the wild [PDF]
Proceedings of the Ninth Biennial ACM Symposium on Eye Tracking Research & Applications, 2016 We present labelled pupils in the wild (LPW), a novel dataset of 66 high-quality, high-speed eye region videos for the development and evaluation of pupil detection algorithms. The videos in our dataset were recorded from 22 participants in everyday locations at about 95 FPS using a state-of-the-art dark-pupil head-mounted eye tracker.
