摘　　要：由于指纹采集设备的不完善性,对于干、湿、脏、老化、磨损的指纹,往往难以采到清晰的图像。本文给出了一套指纹增强的方法,实现了指纹沿指纹方向的图像增强,并针对该算法提出一种有效的去除无效区域的算法。Owing to the defects of fingerprint sampling facilities, it is often difficult to collect the distinct and intact images under the conditions that the finger is too dry , too wet , dirty or frayed. The authors provide a method of Gabor filtering to enhance the images which follows the orientation of fingerprint, and provide an effective method to identify and remove the invalid areas.
