摘要: Iris recognition has gained increasing popularity over the last few decades; however, the stand-off distance in a conventional iris recognition system is too short, which limits its application. In this paper, we propose a novel hardware-software hybrid method to increase the stand-off distance in an iris recognition system. When designing the system hardware, we use an optimized wavefront coding technique to extend the depth of field. To compensate for the blurring of the image caused by wavefront coding, on the software side, the proposed system uses a local patch-based super-resolution method to restore the blurred image to its clear version. The collaborative effect of the new hardware design and software post-processing showed great potential in our experiment. The experimental results showed that such improvement cannot be achieved by using a hardware-or software-only design. The proposed system can increase the capture volume of a conventional iris recognition system by three times and maintain the system's high recognition rate. 其他題名: TCYB 其他題名: IEEE Trans Cybern 出版者: United States: IEEE 出版日期: 2016-12-01 出處: IEEE transactions on cybernetics, 2016-12, Vol.46 (12), p.3342-3350 資源來源: IEEE Electronic Library (IEL) 版權: Copyright The Institute of Electrical and Electronics Engineers, Inc.
