Abstract

Póster y comunicación presentados en 5th European Meeting on Visual and Physiological Optics (EMVPO), Stockholm, 22-24 August 2010.We present a technique for pupil segmentation and contour analysis which will provide valuable information about fixational eye movements. The method is based on fitting an ellipse to the pupil contour. Pupillary hippus, microsaccades and drifts are obtained, as well as cyclotorsional movements.This work has been supported by the Generalitat Valenciana project nr. GV/2009/002

Topics: Eye traking, Eye micromovements, Pupil image segmentation, Óptica
