Exploring human eye behaviour using a model of visual attention

Oyewole Oyekoya and Fred Stentiford presented at the 17th International Conference on Pattern Recognition (ICPR) 2004:

It is natural in a visual search to look at any object that is similar to the target so that it can be recognized and a decision made to end the search. Eye tracking technology offers an intimate and immediate way of interpreting users' behaviors to guide a computer search through large image databases.

This work describes experiments carried out to explore the relationship between gaze behavior and a visual attention model that identifies regions of interest in image data.
Results show that there is a difference in behavior on images that do and do not contain a clear region of interest.
