摘要
提出基于TMS320C6713b浮点型DSP的虹膜识别硬件系统设计,以模块化的方式详细介绍了各个部分的结构、功能、工作原理等设计内容。对归一化的虹膜图像采用2D-Gabor滤波器的虹膜算法实现对虹膜特征的提取,通过比较海明码距完成特征匹配。实验结果表明,该系统能高效、稳定的工作,具有较高的识别率,效果良好。
An iris recognition system is presented based on floating-point DSP TMS3200C6713b.Every system module's constitution,function and principle are discussed in detail.In order to extract iris character,an iris recognition algorithm based 2D-Gabor filter for normalization images is proposed.Through comparing the hamming distance to realize feature match.Experiment results show that this system can run efficiently and stability,which has higher recognition accuracy and good effect.
