A visual attention approach to personal identification
Anthony John Maeder, Clinton Fookes · QUT ePrints (Queensland University of Technology) · 2003
This paper describes the use of visual attention charac-teristics, monitored by gaze tracking during presentation of a known visual scene to a viewer, as a biometric for dis-tinguishing between individual viewers. The positions and sequences of gaze locations during viewing may be deter-mined by overt (conscious) or covert (sub-conscious) view-ing behaviour. Methods to quantify the spatial and tempo-ral patterns established by the viewer for a particular image are proposed, and distance measures between these are es-tablished. Experimental results suggest that both types of gaze behaviours can provide simple and effective biomet-rics for this application. 1.
