| 摘 要： | 指纹图像预处理需针对不同的噪声产生原因而采用不同的方法，先对采集到的退化图像进行Wiener滤波。然后对复原后的图像进行增强预处理．着重对主要预处理方法Gabor方法和各向异性扩散技术进行了分析对比，并就这些方法中的参数选择进行了对比研究．

| Abstract: | The fingerprint image pre-processing is conducted by different ways according to different reasons.It firstly applies Wiener filtering to the degraded images,and then make an enhancement pretreatment to the recovered images.It focuses on comparison and analysis of the key methods of the Gabor and anisotropic diffusion,and also conducts a comparison research in the parameter selection used in these methods. |

| Keywords: | Wiener filtering Gabor filtering anisotropic diffusion fingerprint image |
