本文提出了一种新的指纹图像质量检测方法。用于这种目的的一些度量是公知的，例如图像中的灰度信息的对比度差或平均值。这些方法在开始时被简短地提到，但本文的主要目标是提出一种新的方法来评估指纹图像，它可以指示图像是否适合进一步处理或不。该方法测试某些乳头线的横切是否不同于理想情况下的乳头线（正弦曲线）。
This paper deals with a new approach for the fingerprint image quality testing. Some metrics for such purpose are well known - e.g. contrast differences or the average value of grayscale information in an image. These methods are shortly mentioned at the beginning, but the main goal of this article is to present a new method for the evaluation of fingerprint image which can indicate whether an image is suitable for further processing or not. The method tests whether the crosscut of some papillary line differs from the ideal case of papillary line (a sinusoidal curve).
