摘    要:准确地进行指纹中心点定位,对指纹分类和匹配有重要意义。本文提出一种复合的指纹中心点定位算法,在指纹分块基础上,利用方向能量进行初步搜索,再用块的庞加莱算法进行二次定位。该算法快速,简单,鲁棒性好。

关 键 词:指纹中心点  方向能量  块庞加莱指数

Abstract:Locating the core point of fingerprint accurately is of great importance for fingerprint classification and matching.This paper presents a compound algorithm for locating the core point of fingerprint which searches fingerprint images first according to the directional energy on the base of fingerprint blocking and then locates the core point using the block-based Poincare index analysis.The proposed algorithm is effective, simple and robust to noise.
Keywords:core point of fingerprint  directional energy  block-based Poincare index
