摘要
指纹预处理对于指纹特征提取和匹配有着至关重要的作用。详细介绍了指纹预处理包括滤波、二值化、细化及去噪的思路 ,并给出部分程序流程图。编程实践证明 。
Preprocessing in fingerprint identification is critical to subsequent feature extracting and matching.Introduces the preprocessing including filtering in grey picture, binarization, thinning and filtering as well as partial flow charts. The results show that good effect has been obtained.
