【摘要】 提出了一种空间信息与尺度信息相结合的虹膜识别算法。将二维小波变换与灰度共生矩阵相结合,由此提取的虹膜特征向量既反映了空间变化的特性也反映了尺度变化的特性。实验结果表明用该方法构造的虹膜识别算法,对比仅用小波变换的方法,可获得较高的识别率。更多还原

【Abstract】 It proposed an algorithm of iris recognition based on combination of spatial information and scale information. The combination of 2-dimension wavelet transform and gray-level co-occurrence matrix is presented, and eigenvector of iris is extracted by this method, which reflects features of spatial transformation and scale transformation. The experimental results show that the algorithm of iris recognition has higher recognition rate in contrast with the algorithm based on wavelet transform.更多还原
