We propose a fingerprint coding algorithm based on directional image, EZW and MRWD algorithm.
在深入研究EZW和MRWD方法基础上，提出了一种结合指纹方向图的指纹压缩算法。
Firstly gain the continuously directional image of the fingerprint, secondly design orientation template using the directional image and filter the fingerprint image, lastly obtain the binary image.
先得到指纹图像的连续方向图，再根据此方向图设计方向滤波模板进行滤波，最后得到指纹的二值化图像。
