| 摘 要： | 针对残缺指纹中方向场的重构,本文提出了一种利用全局方向信息和局部梯度信息的基于互信息准则的方向场融合算法此算法根据局部梯度信息的竞争性、结合全局方向信息的互补性、冗余性,首先根据局部指纹梯度信息定义离散度,自适应的融合梯度信息,其次运用互信息准则结合指纹全局信息,对残缺部分的方向进行重估和修正根据融合结果,进行后期指纹...

| Abstract: | Based on the global orientation,the local gradient and the mutual information function,a novel fingerprint orientation field fusion algorithm is proposed for incomplete fingerprint orientation field reconstruction.First,according to the properties of competition of the local fingerprint,complementation and redundancy of the global fingerprint,the gradient dispersion function is proposed,adaptively.Then,the fingerprint orientation field of the incomplete area is re-computed and measured by mutual information... |
