Abstract

We report on an iris recognition system using image sequences instead of single still images for recognition. Image sequences captured at different focus levels provides more information than single still images. Most of the current state-of-the-art iris recognition systems use single still images which are highly focused. These systems does not recognize defocused iris images. The experimental results show that defocused iris images can be correctly recognized if we use multifocus image sequences as gallery images for recognition.
