Description: 介绍并实现了一套完整的指纹图像预处理方法,通过剩余块处理和平滑方法改进了传统 的指纹图像分割算法 使用方向匹配的方法对指纹图像方向块进行方向滤波完成图像增强 并除去细化后存在的短线和毛刺。该算法对Secugen指纹仪采集的图像和FVC2004数据库中的指纹图像进行实验,结果表明经过预处理后的指纹图像质量得到明显增强,方便进行细节特征提取。-Introduction and realize a complete set of fingerprint image pre-processing methods, and treatment through the remaining block smoothing method to improve the traditional fingerprint image segmentation algorithm using the direction of matching the method of fingerprint image filtering direction the direction of block completion of image enhancement and refinement to remove after the the existence of short-term and burr. The algorithm for fingerprint Secugen Miriam Collection FVC2004 images and fingerprint images in the database to conduct experiments, results showed that after pretreatment of the fingerprint image quality has been markedly enhanced, to facilitate the details of feature extraction.
