| 摘 要： | 掌纹因稳定性、唯一性、难复制性及易获取等特点，是极具应用潜力的生物识别特征。针对掌纹识别中，获取掌纹感兴趣区域（ROI）与增强掌纹信息普遍存在的时间成本大，方法之间有依赖关系等问题，提出了一种基于U-Net神经网络结构的掌纹图像预处理方法。通过香港理工大学掌纹库进行实验对比，结果表明，所提方法能消除预处理方法之间的相互影响，实现对掌纹图像的去噪与增强处理，并能快速、高精度提取感兴趣区域。

| Abstract: | Palmprint is a biometric feature with great application potential due to its stability, uniqueness, hardness in copying, and easy access.In the palmprint recognition, palmprint Region of Interest(ROI) acquisition and palmprint enhancement usually have the problems of high time cost and high dependency between methods.This paper proposes a palmprint preprocessing method based on U-Net neural network structure.The experiments are carried out on palmprint database from Hong Kong Polytechnic University.The results show that the proposed method can eliminate the mutual influence between the preprocessing methods.Both denoising and enhancement of palmprint images are realized, and the region of interest can be extracted quickly and accurately; plamprint |
