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。
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.
