中文摘要：
低质量指纹通常被定义为模糊、高噪声、低对比度等情况下的指纹。利用人体固有的指纹生理特征来进行个人身份鉴定的指纹识别技术中，图像增强技术是其中一个非常重要的步骤。低质量指纹图像增强效果直接影响低质量指纹图像的识别效果。文中在简介指纹识别过程的基础上，以一种典型的低质量指纹图像增强算法一Gabor滤波增强算法为例，重点阐述了MatlabGUI设计的一般步骤及其在低质量指纹图像增强中的具体实现。对用户开发MatlabGUI应用程序和利用GUI处理图像等相关问题都有一定的借鉴意义。
英文摘要：
The low quality fingerprint is usually defined as fingerprint which is fuzzy, noisy and low-contrast. Among the fingerprint identification technique which based on the intrinsic physiological property of fingerprint, image enhancement technology is an all-important one. The enhancement will directly affect the recognition effect of low-quality fingerprint image. Based on the introduction of the finger- print recognition process, focus on the steps of the Matlab GUI design and its realization in the enhancement of the low quality fingerprint image, with Gabor filtering enhancement algorithm-a typical low-quality fingerprint image enhancement algorithm as example. There is certain reference significance for the user developing Maflab GUI application program and using GUI to process image, etc.
