High Speed Pupillometry

Abstract

Measuring the parameters of the pupil in the human eye has become increasingly important in customised refractive surgery and other eye care applications. High-speed and high resolution CMOS cameras can be used to study the dynamics of eyelids and their interaction with the pupil at different illumination levels. We consider the problem of measuring the pupil size from a high-speed video. In particular, we develop a novel algorithm for setting intra-lid sectors for the detection and estimation of the pupil and iris outlines from a sequence of digital images. An application of the proposed methodology to the estimation of the pupil parameters during an eye blink is given.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
