Iris Perturbation Methods for Improved Recognition

Master's Thesis


Perturbations of software provided circular segmentations are used to generate multiple probe templates from a single image. The multiple probes are matched against a gallery in order to improve the verification rate of the original algorithm. Using too many of the generated probes will result in greatly increased running times. As a result, various methods of finding and selecting perturbations to be used are empirically examined. Using ROC analysis of the true accept rate (TAR) at a given false accept rate of 0.001, many methods are discovered that perform much better than the original algorithm, approximate the performance of using every perturbation to less than 0.2%, and require between 500 to 1000 times less time to verify a single image.
