Analysis of fixational eye micromovements through pupil tracking

Póster presentado en OPTYKA Optical Fair 2012, Poznan, Polonia, 9-10 noviembre 2012.

The human eye is constantly moving even when it is maintaining a stable fixation point. Stable images on the retina rapidly saturate the photoreceptors and fade. The visual system needs of constant stimulation is achieved by fixation micromovements consisting of microtremors, drifts and microsaccades. We present a technique for pupil segmentation and contour analysis which will provide valuable information about fixational eye movements.
