摘要
针对由滑动指纹采集仪获取的指纹图像序列的特点,提出了一种具有较高精确度的滑动指纹序列拼接算法.该算法利用扩展相位相关方法来估测相邻两帧指纹图像之间的平移量,并进行指纹序列的无缝拼接.实验结果表明,该算法具有运行速度快、对随机噪声的抗干扰能力强和拼接精确度高的特点.
A highly accurate and eomputationally efficient method suitable for the mosaic of swipe fingerprint sequences was presented. The method is based on the extension of the well-known phase correlation technique and can robustly estimate large translations between two consecutive frames with subpixel accuracy. The experimental results show that the method has less time consumption and more robustness against noise and superior precision.
