Semi-Supervised Learning for Eye Image Segmentation

no code implementations17 Mar 2021 Aayush K. Chaudhary, Prashnna K. Gyawali, Linwei Wang, Jeff B. Pelz

Recent advances in appearance-based models have shown improved eye tracking performance in difficult scenarios like occlusion due to eyelashes, eyelids or camera placement, and environmental reflections on the cornea and glasses.

$pi_t$- Enhancing the Precision of Eye Tracking using Iris Feature Motion Vectors

no code implementations20 Sep 2020 Aayush K. Chaudhary, Jeff B. Pelz

A new high-precision eye-tracking method has been demonstrated recently by tracking the motion of iris features rather than by exploiting pupil edges.

EllSeg: An Ellipse Segmentation Framework for Robust Gaze Tracking

3 code implementations19 Jul 2020 Rakshit S. Kothari, Aayush K. Chaudhary, Reynold J. Bailey, Jeff B. Pelz, Gabriel J. Diaz

Ellipse fitting, an essential component in pupil or iris tracking based video oculography, is performed on previously segmented eye parts generated using various computer vision techniques.

RITnet: Real-time Semantic Segmentation of the Eye for Gaze Tracking

2 code implementations1 Oct 2019 Aayush K. Chaudhary, Rakshit Kothari, Manoj Acharya, Shusil Dangi, Nitinraj Nair, Reynold Bailey, Christopher Kanan, Gabriel Diaz, Jeff B. Pelz

Accurate eye segmentation can improve eye-gaze estimation and support interactive computing based on visual attention; however, existing eye segmentation methods suffer from issues such as person-dependent accuracy, lack of robustness, and an inability to be run in real-time.
