“…Ma et al [19] also enrolled three iris images and averaged the three Hamming distances to obtain the final score. Krischen et al [20] used the minimum of the three Hamming distance as the final score. Schmid et al [21] demonstrated that fusing the scores using log likelihood ratio gave superior performance when compared to average Hamming distance.…”

Abstract-Non-contact biometrics such as face and iris have additional benefits over contact based biometrics such as fingerprint and hand geometry. However, three important challenges need to be addressed in a non-contact biometrics-based authentication system: ability to handle unconstrained acquisition, robust and accurate matching and privacy enhancement without compromising security. In this paper, we propose a unified framework based on random projections and sparse representations, that can simultaneously address all the three issues mentioned above in relation to iris biometrics. Our proposed quality measure can handle segmentation errors and a wide variety of possible artifacts during iris acquisition. We demonstrate how the proposed approach can be easily extended to handle alignment variations and recognition from iris videos, resulting in a robust and accurate system. The proposed approach includes enhancements to privacy and security by providing ways to create cancelable iris templates. Results on public datasets show significant benefits of the proposed approach.

“…Ma et al [4] also used three templates of a given iris in their enrollment database, and took the average of three scores as the final matching score. Krichen et al [5] performed a similar experiment, but used the minimum match score instead of the average. Schmid et al [6] present two methods for fusing Hamming distance scores.…”

“…Iris recognition is no exception. Many researchers [4,5,6] enroll multiple images, obtain multiple Hamming distance scores, and then fuse the scores together to make a decision. However, the different researchers have chosen different ways to combine the information from multiple Hamming distance scores.…”

“…We postulated that employing similar techniques for iris recognition could also yield improved performance. There is some prior research in iris recognition that uses multiple still images; for example, [3,4,5,6]. However, no researchers have published on how to use additional information available in iris video.…”

Abstract. We take advantage of the temporal continuity in an iris video to improve matching performance using signal-level fusion. From multiple frames of an iris video, we create a single average image. Our signal-level fusion method performs better than methods based on single still images, and better than previously published multi-gallery scorefusion methods. We compare our signal fusion method with another new method: a multi-gallery, multi-probe score fusion method. Between these two new methods, the multi-gallery, multi-probe score fusion has slightly better recognition performance, while the signal fusion has significant advantages in memory and computation requirements.
