摘要
特征匹配是虹膜识别的一个重要步骤,直接影响了虹膜识别率的高低。由于基于结构虹膜特征点的特殊性,采取了特殊的匹配算法,即面积加权自定位匹配法。实验结果证明,可以本质上提升基于结构特征的虹膜识别算法的识别率,使其达到准实用的水平。
The character matching is one important step of iris recognition, and it influences iris recognition rate. As a result of particularity based on the structure iris character point, this paper has adopted the special matching algorithm, namely area weighting. The experimental result proved that it may promote essentially recognition rate of recognition algorithm based on the structural character iris, and enables it to achieve the practical level.
