![]() ![]() In order to protect our IPR in the design of iris camera (especially the NIR illumination scheme) before appropriate patents were granted, the pupil regions of all iris images in CASIA-IrisV1 were automatically detected and replaced with a circular region of constant intensity to mask out the specular reflections from the NIR illuminators before public release. Eight 850nm NIR illuminators are circularly arranged around the sensor to make sure that iris is uniformly and adequately illuminated. Iris images of CASIA V1.0 (CASIA-IrisV1) were captured with a homemade iris camera. To promote the research, National Laboratory of Pattern Recognition (NLPR), Institute of Automation (IA), Chinese Academy of Sciences (CAS) will provide iris database freely for iris recognition researchers. Lacking of iris data may be a block to the research of iris recognition. There is not any public iris database while there are many face and fingerprint databases. Introduction Iris recognition has been an active research topic in recent years because of its high accuracy. ![]()
