| 摘 要： | 在自动识别系统中，为了消除噪声以提高指纹图象的质量，采用梯度法计算指纹图像的方向图，通过构造一组方向滤波器对指纹图像进行滤波，然后提出了一种针对方向滤波后的指纹图像消除噪声的方法，试验结果表明了该方法的有效性和实用性。

| Abstract: | In order to enhance the the gradient method is adopted to filters are constructed to filter the the filtered imagines. Test results quality of fingerprint image in the automatic identification system, calculate the directional image of fingerprint. A set of orientation fingerprint images. A method is proposed to eliminate the noise in prove the method effective and practical. |
