In this paper, we introduce the Minutia Cylinder-Code (MCC): a novel representation based on 3D data structures (called cylinders), built from minutiae distances and angles. The cylinders can be created starting from a subset of the mandatory features (minutiae position and direction) defined by standards like ISO/IEC 19794-2 (2005). Thanks to the cylinder invariance, fixed-length, and bit-oriented coding, some simple but very effective metrics can be defined to compute local similarities and to consolidate them into a global score. Extensive experiments over FVC2006 databases prove the superiority of MCC with respect to three well-known techniques and demonstrate the feasibility of obtaining a very effective (and interoperable) fingerprint recognition implementation for light architectures.
在本文中，我们介绍了 Minutia Cylinder-Code（MCC）：一种基于 3D 数据结构（称为圆柱体）的新型表示，由细节距离和角度构建而成。圆柱体可以从标准（如 ISO/IEC 19794-2（2005））定义的强制特征（细节位置和方向）子集开始创建。由于圆柱体不变性、固定长度和面向位的编码，可以定义一些简单但非常有效的度量标准来计算局部相似度，并将它们合并为全局得分。在 FVC2006 数据库上进行的广泛实验证明了 MCC 相对于三种知名技术的优越性，并证明了为轻量级体系结构获得非常有效（且可互操作）的指纹识别实现的可行性。
