With several quality factors proposed for iris images, its specific effect in the segmentation accuracy is often obviated, with most of the efforts focused on its impact in the recognition accuracy. Accordingly, we evaluate the impact of 8 quality measures in the performance of iris segmentation. We use a database acquired with a close-up iris sensor and built-in quality checking process. Despite the latter, we report differences in behavior, with some measures clearly predicting the segmentation performance, while others giving inconclusive results. Recognition experiments with two matchers also show that segmentation and matching performance are not necessarily affected by the same factors. The resilience of one matcher to segmentation inaccuracies also suggest that segmentation errors due to low image quality are not necessarily revealed by the matcher, pointing out the importance of separate evaluation of the segmentation accuracy. © 2013 IEEE.</p> ICB-2013, The 6th IAPR International Conference on Biometrics, Madrid, Spain, June 4-7, 2013 http://dx.doi.org/10.1109/ICB.2013.6613016 http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:607425 Proceedings – 2013 International Conference on Biometrics, ICB 2013 Conference Paper Article number 6613016 Quality Factors Affecting Iris Segmentation and Matching 2013 2016-09-30T20:41:45Z 2457662.3623264 Quality Factors Affecting Iris Segmentation and Matching 500 0 plainlist list 1 [[:Publications:Quality Factors Affecting Iris Segmentation and Matching]] Quality Factors Affecting Iris Segmentation and Matching# QUERY4323d1a8f8b5c4840a8f35e43ef389f0 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Quality Factors Affecting Iris Segmentation and Matching# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Quality Factors Affecting Iris Segmentation and Matching# ERRe24f17e090c98448f3de99d03182b7b6
