| 摘 要： | 基于Gabor滤波器的指纹图像质量分区方法，对指纹图像的各个分区进行了质量评价。然后对高质量分区直接进行脊线跟踪．提取细节特征点；对低质量分区先使用普遍使用的预处理方法，再进行特征提取。对著干幅低质量指纹进行了实验，得到了不错的实验效果，并且实验的效率和准确率也有所提高。

| Abstract: | A method of the districts divided by image quality base on Gabor filter, The image quality of all districts is estimated . Ridges are traced and minutiae are extracted directly from the high-quality districts; the ordinary methods of preprocessing are executed for poor-quality districts, and then minutiae are extracted. Some poor-quality images were tested, and good result was obtained. The right rate and efficiency of Minutiae Extraction was improved. |
