摘要
深入研究了指纹图像二值化算法,提出一种基于指纹方向图的模糊二值化算法,算法根据指纹方向图的特性,引入了模糊数学的理论,能够在保持特征点不丢失的基础上完成一般指纹图像处理中的滤波和二值化的处理。
Based on the research on binarization algorithms of fingerprint images, a new binarization algorithm of fingerprint images based on the orientation and fuzzy theory was put forward. The method made full use of the orientation and the characteristics of grayscale change and demonstrated the excellent capability of noise resistance.
