Comparison of Experts and Non-Experts Gaze Pattern for the Target as Optic Disc in the Fundus Retinal Images

摘要

The proposed paper presents a significant study done in the field of the medical domain to identify the differences in eye gaze patterns between two groups, the first group is expert optometrists and the second group is non-experts. Eye gaze data is collected through commercial eye tracker during the task of detecting the optic disc in given fundus retinal images. The eye fixations were calculated using dispersion threshold identification (I-DT) algorithm. The heat maps were used for visualization. The set of eye movement features, a number of fixations, duration of fixation in ROI, the number of dwells in ROI, dwell time in the ROI, the number of fixations in the region of interest (ROI) and the energy concentration ratio was estimated to prove the statistically significant difference between the eye gaze patterns.
