摘要
图像分割是指纹图像预处理中的重要步骤 ,单独使用常用的方差法和方向法 ,效果往往不是很好 ,但它们各有所长 ,优缺点互补 ,本文介绍了一种基于方差法和方向法的合成分割算法 。
The image segmentation is the important procedure in the processing for fingerprint images; it is hard to have perfect effect if using variance method and direction method individually. But each of them has its own advantages, so they can be used compoundly for complement. In the paper, a compound algorithm based on variance method and direction method is introduced. Our experiments show that method is satisfactory.
