标准范围
ISO/IEC 19794-3:2006,指纹图谱光谱数据交换格式,规定了从指纹图像中导出的局部或全局光谱数据的表示要求。该格式被设计为在频谱表示的选择上提供灵活性,因为频谱分量可以基于量化的共正弦三元组、离散傅立叶变换或Gabor滤波器。该格式还允许保留可变数量的光谱分量,这使得数据表示的形式比整个指纹图像的存储更紧凑。ISO/IEC 19794-3:2006提供了每个光谱表示的示例数据记录。
ISO/IEC 19794-3:2006, the finger pattern spectral data interchange format, specifies requirements for the representation of local or global spectral data derived from a fingerprint image. The format is designed to provide flexibility in the choice of spectral representation in that spectral components may be based on quantized co-sinusoidal triplets, Discrete Fourier Transformations or Gabor filters. The format also allows for a variable number of spectral components to be retained, which enables data representations in a form that is more compact than storage of the entire fingerprint image. ISO/IEC 19794-3:2006 provides example data records for each of the spectral representations.
