摘　　要：基于自适应动态阈值分割算法,针对采集的指纹图像灰度值不均特点加以改进,提出了一种改进的指纹图像分割算法,结合阈值分割与区域分割,从而使指纹的背景和目标区分开来,这样处理出来的指纹图像效果更好.实验证明,本文提出的指纹图像分割算法能达到很好的指纹图像处理效果.This paper makes a study of fingerprint image segmentation algorithm. Fingerprint image segmentation algorithm is the essence of the whole fingerprint identification system. The paper presents an improved fingerprint segmentation algorithm. Based on adaptive dynamic threshold segmentation algorithm for fngerprint image, the paper has collected uneven gray value characteristics to improve the algorithm. The paper presents an improved fngerprint image segmentation algorithm, and it combines threshold segmentation algorithm and region segmentation algorithm. According to the experiments, these algorithms introduced in the paper can be tested in PC by programming. Through the comparison and analysis of these algorithms, it has been proved that the algorithm described in the paper has a great advantage in fngerprint image processing.
