| 摘 要： | 方向加权中值滤波算法是一种新的滤波方法。该方法用于指纹二值化图象处理主要是充分运用指纹方向图和模糊理论思想来构造滤波模板，其算法简单，处理速度快，而且当方向不准确时，也可给出较正确的结果，因而大大增强了算法的抗干扰性。

| Abstract: | A new filtering algorithm, i.e., the directional medial filter ing with weights is proposed. The directional image of the fingerprint and the i dea of the fuzzy theory are utilized to construct filtering template, so the met hod is simple and the speed is high. Moreover, comparatively correct result can be worked out when the direction isn't exact, which strengthens the capability o f the algorithm against disturbance. |
