一种新的指纹图象细化算法
摘 要
针对OPTA细化算法存在的不足，即细化不全，速度较慢的缺点进行分析和研究，提出了一种新的细化算法，该算法速度快，细化全，细化后的指纹骨架在纹线中心线，且光滑无毛刺。

A New Thinning Algorithm for Fingerprint Image
() Abstract
The disadvantages of the OPTA thinning algorithm, i.e. incomplete thinning and slow speed, are analyzed and studied. A new algorithm is presented which has the advantage of quick speed and complete thinning. The thinned fingerprint skeleton is smooth and located in the center of the ridge.
