- Abstract
- In conventional iris recognition camera, it is very difficult to capture the focused iris image at fast speed due to small range of DOF(Depth Of Field) in iris camera. So. we introduce a fast focusing method to capture user's focused iris image based on the corneal specular reflection and the human eye model. According to experimental results, we can reduce the focusing time of proposed method to be 450 ms on average. © Springer-Verlag Berlin Heidelberg 2005.
