摘要
讨论了虹膜识别技术的虹膜特征提取及编码，提出了一种基于Ｇａｂｏｒ函数集的编码方法，利用Ｇａｂｏｒ滤波器的相位特征，对虹膜纹理进行编码．同时，针对此编码又提出了基于加权海明距离的识别方法，并阐述了其实际识别效果．实验结果证明，该方法具有良好的编码效果及很高的运算速度，是目前较好的一种虹膜纹理编码方法．
The extraction of iris characters and its encoding method were discussed. A new encoding algorithm based on Gabor filters was proposed. This algorithm utilizes the phase characters of Gabor function to encode iris texture. A pattern matching algorithm based on weight Hamming distance was discussed for this kind of iris codes. The result of experiment shows that this encoding method has a good recognition effect and very high speed of operation. It is a good iris texture encoding algorithm presently known.
