Paper Abstract

The iris contains fibrous structures of various sizes and orientations which can be used for human identification. Drawing from a directional energy iris identification technique, this paper investigates the size, orientation, and location of the iris structures that hold stable discriminatory information. Template height, template width, filter size, and the number of filter orientations were investigated for their individual and combined impact on identification accuracy. Further, the iris was segmented into annuli and radial sectors to determine in which portions of the iris the best discriminatory information is found. Over 2 billion template comparisons were performed to produce this analysis.
