专业释义
- 纹线距离估计
Automatic fingerprint identification system(AFIS) often contains fingerprint acquisition, fingerprint preprocessing, fingerprint matching, where fingerprint preprocessing includes normalization, fingerprint segmentation, orientation computation, ridge distance estimation, fingerprint enhancement, fingerprint binarization, fingerprint thinning, feature extraction.
自动指纹识别系统(AFIS)通常包括指纹采集、指纹预处理、指纹匹配三个阶段。 而指纹预处理又包括标准化、指纹分割、方向场求取、纹线距离估计、指纹增强、二值化、细化、特征提取等步骤。
