摘要
该文介绍了一种指纹图像的预处理算法,实验结果表明这种算法能有效地去除采集到的指纹图像的噪声,自适应地增强指纹图像的脊和谷的结构,标记出有效的指纹区域和无效的指纹区域,同时具有较快的速度。
In this paper a fingerprint image pre-procession algorithm is proposed,the experimental results show it has the fine enhancement effect on the polluted fingerprint images.This algorithm can not only enhance the ridge and valley of a fingerprint image,but also mark up the valid and invalid fingerprint ranges.And at the same time it has faster speed.
