Three Cs of Advanced Iris Biometrics:
Crypts, Cosmetics, and Contact Lenses

As iris recognition products continue to enter the market and the research area matures, efforts to broaden the scope and capability of iris recognition are emerging. Research on recognition from less constrained data with a wider diversity of subject attributes has created fertile ground for topical studies. In this presentation, we will motivate and discuss new work on:

1. Iris identification using crypt and anticrypt features that can be annotated by humans and therefore are of potential use in a forensic investigation context with humans in the loop.
2. Classification of ocular images with respect to the presence or absence of contact lenses.
3. Performance of iris recognition systems in the presence or absence of mascara.
