Detection of Parkinson's Disease Through Automated Pupil Tracking of the Post-illumination Pupillary Response
2021
Frontiers in Medicine
Preserved Fulltext
Tracking the pupil size manually is a tedious process and offline automated systems can be prone to errors that may require intervention; for this reason in this work we describe a system for pupil size ...
Tracking was automated using a Kalman filter estimating the pupil center and diameter over time. ...
The tracking of pupil direction and size has a variety of applications, and Kalman filters provide a robust means of estimating size over time in a variety of contexts. ...

This includes methods to effectively and robustly detect and track glints and pupils in the context of high-speed remote eye tracking, which, paired with a geometric eye model, achieved an average gaze ...
In this paper, we present and evaluate a system designed to track such high-speed eye movements, achieving operating frequencies well beyond 500 Hz. ...
The Kalman filter can be problematic for the pupil signal, as pupil movements can be very fast and create far jumps in the image. ...
