摘要
首先介绍指纹图像分割的基本概念,接着使用一种基于标准差的图像分割算法对指纹图像进行分割.该方法利用标准差找出最佳分割阈值,再用该阈值将指纹图像脊线提取出来.实验结果表明,该方法能够很好地将指纹脊线从背景中提取出来.
This paper introduced the bas ting algorithm based on standard deviatio gorithm could find the best Segmentation ic concept of fingerprint image segmentation, then a segmen- n was used to process fingerprint images. This segmenting al- of threshold and extract fingerprint ridge from the image. The test results indicated that this method did well at the extraction of fingerprint ridge.
