Use of Artificial Color filtering to improve iris recognition and searching

摘要

Iris recognition and searching are attractive in biometrics for many reasons. The spatial patterns have been studied and recognized effectively for several years. They are more complex than fingerprints. We suggest here that the relatively new field of Artificial Color filtering can provide an orthogonal discriminant to the spatial pattern discriminant. We also show how to combine results from the two discriminants in such a way as to improve performance of the combined system over either part-something that has been troubling until now.
