摘要

在本文中，我们证明了小波变换是一种有效的技术，可以显著压缩指纹图像，同时保留准确识别所需的结构细节。本文提出了一种用于自动指纹匹配系统的基本识别特征提取算法。与现有算法相反，本文提出的方法在压缩/解压缩指纹图像上进行了测试。我们表明，使用作者之前提出的压缩算法，我们能够在压缩比低至50:1的情况下获得有效的指纹描述。

An algorithm for reducing the effect of compression/decompression techniques on fmgerprint minutiae

We show in this paper that the wavelet transform is an effective technique for significantly compressing fingerprint images, while retaining the necessary structural details for accurate identification. The paper presents a new algorithm for extracting the fundamental identification features for use in automated fingerprint matching systems. Contrary to existing algorithms, the method presented here is tested on compressed/decompressed fingerprint images. We show that using the compression algorithm proposed earlier by the author, we are able to obtain a valid description of the fingerprints at compression ratios down to 50:1.
