摘　　要：对指纹图像细化后算法进行研究,分析了常规细化后处理算法存在的不足,分析其产生的原因,并在常规细化后算法的基础上提出了一种改进的细化后算法。经过实验表明,该算法在继承了原有细化后算法优点的基础上显著地减少了细化后的噪声,是一种较为理想的细化后算法。The post-thinning for fingerprint images is studied in this article.The disadvantages of the common post-thinning algorithm is analyzed,and the reasons of these disadvantages are invertigated.A improved post-thinning algorithm is proposed on the base of the common post-thinning algorithm.Through lots of experiments,the algorithm has been proved to a better post-thinning algorithm which inherits advantages of other ones and can significantly reduce the noise in the post-thinning process.
