摘要
介绍了分数阶微积分及其性质,提出了一种分数阶微分掩模算子的实现方案,并将其应用于模糊指纹图像增强中.实验结果表明,利用该技术处理后的指纹图像具有清晰度高、实用性好等特点.
In this paper, the history and property of Fractional-Order Calculus（FOC） are introduced briefly. Fractional differential cover operator for digital image processing is presented and this technique applied in blur fingerprint imagese enhancement. Experimental results indicate that the technique has the advantages of high definition, good practicability et al.
