ABSTRACT: Awarded Best Paper, Biometrics and Forensics
We design and implement a hyper-focal imaging system for acquiring iris images in the visible spectrum. The proposed system uses a DSLR Canon T2i camera and an Okii controller to capture videos of the ocular region at multiple focal lengths. The ensuing frames are fused in order to yield a single image with higher fidelity. Further, the proposed setup extends the imaging depth-of-field (DOF), thereby preempting the need for employing expensive cameras for increased DOF. Experiments convey the benefits of utilizing a hyper-focal system over a traditional fixed-focus system for performing iris recognition in the visible spectrum. Download the full article.
