| 摘 要： | 研究指纹的方向图对实现指纹纹线修补、纹形特征的提取以及指纹的分类等应用都有很强的实用价值。笔者通过对指纹图象方向基元集的定义和描述，运用方向基元样本的统计特性，给出了一种求取指纹方向图的方法。并将该方法运用到一套智能卡指纹验证系统中进行纹型比对，实践证明：该方法算法简单，快速有效，对各种噪声具有一定的鲁棒性。

| Abstract: | By the definition and interpretation of directional elemental pixel sets, a method for getting the directional image from the binary fingerprint image using the statistic characteristics of DEPS is presented in this paper. This method is better than traditional methods in processing speed, computing complexity and resisting noises. The directional image got by this method is used to the matching of ridges frame in a fingerprint verification system, and the testing result shows that the method is effective. |
