- 信息技术－已发表论文 
对指纹图像算法进行了较深入的研究,分析了OPTA算法和改进的OPTA算法的优缺点,提出了一种新的细化算法,经过实验证明,该算法能够很好的满足细化的要求,细化完全彻底,细化后保持了纹线原有的拓扑结构和细化特征,而且光滑无毛刺,运算速度也很快。The thinning algorithm for fingerprint image is studied deeply in this article. Moreover , Both the advantages and disadvantages of OPTA and the improved OPTA thinning algorithm are analyzed., and a new improved algorithm is presented. Through experiments, the new algorithm has been proved to have many advantages such as complete thinning, quick speed, smooth skeleton, maintenance of minutiae, an so on.
