指纹图像二值化方法的比较研究
Comparative study among fingerprint image binarization methods
【摘要】 对常用的指纹图像二值化方法进行了比较研究.在此基础上对文献[1]提出的指纹图像二值化方法进行了改进,并对二值化图像、后续的细化图像和特征点提取结果进行了比较.
【Abstract】 In this paper,common fingerprint image binarization methods were compared and analyzed.On the basis of this,a fingerprint image binarization method presented by LUO Xi-ping et al is improved.And not only did we make a comparison of their binarization images,but make that of their subsequemt thinning images and minutia extracted.
