Abstract:
The accuracy of the orientation map will have a great influence on the subsequent process in processing a fingerprint image,so how to compute the fingerprint orientation map accurately comes to be very important.This paper presents two main algorithms comparatively for practical application.
摘要: 在指纹图像处理中方向图计算的精确性对于后继处理步骤有很大影响,所以研究指纹方向图的提取算法显得格外重要。指纹方向图提取的算法有很多,该文分别给出点方向图和块方向图两类重要的算法,实验证明了其可靠性。
