摘　　要：在指纹库中,实际采集到的捺印指纹大多数有边框线,这就造成自动指纹识别系统对中心点定位的错误判断和对图像背景区域无法分割,从而导致该指纹无法检出。根据数据库的实际需要,提出了一种针对指纹边框线的滤除算法,有效地解决了这个问题,并通过实验证实了该算法的可靠性。In fingerprint storeroom, most of the press fingerprint collected has fringe line, which brought some troubles to the automated fingerprint identification system＇ s accurately positioning the center place and dividing the image background ; therefore, the fingerprint cannot be checked out. To meet the real needs of the database, this essay advocates a deleting arithmetic to eliminate the fringe line in fingerprint, which effectively solved the problem and has been proven reliable in the test.
