| 摘 要： | 为了提高虹膜识别的速度和准确性，提出一种新的虹膜图像均衡法：将直方图均衡法和局部对比度增强法结合起来调节图像动态范围、增强局部对比度，并利用平衡式零谱矩滤波器对预处理后的虹膜图像进行分解，提取更准确的虹膜纹理特征。整个虹膜识别过程小于1．3s，准确率97．25％。可用于个人身份识别中。

| Abstract: | In order to improve the speed and accuracy of iris recognition, a new iris image balance algorithm is developed ： Histogram equalization and part contrast enhancement are combined to adjust development range and enhance the part contrast. Zero spectral moment filters were used to decompose the pre-processing iris image for getting more exact iris texture features. The whole iris recognition process requires less 1.3 s and achieves an identification rate of 97.25%. it can be used in a personal i- dentification system. |
