基于空间滤波及子区域截取的虹膜识别系统设计

System design based on space filter and sub-area cutting

基于虹膜图像的纹理特征展开分析,得出其在斑点、细丝、条纹、隐窝等空间性状方面的表现决定了个体信息的唯一性。提出了基于空间滤波并子区域截取的特征提取方法,结合应用BP神经网络进行模式识别。最后对处理结果进行对比分析,并得出结论。

This paper analyzed the character of irises＇ texture, got the conclusion that the appearance of irises＇ spots, filaments, stripes and recesses determine the exclusive quality of individual. An novel method of abstracting eigenvector was proposed based on space filter and sub area cutting. Finally, a BP Nerval Network was built to recognize samples. At the end of the paper the processing results was analyzed and the conclusion was drawn.
