    • A noise-component removing method for removing a noise component from multipoint spectral data that has been generated through measurements performed at measurement points of a sample surface, the method comprising: a PLS analysis step of determining components of the multipoint spectral data for each measurement point in a descending order of eigenvalues of the components by subjecting the multipoint spectral data to multivariate analysis based on the partial least squares regression using a value obtained by quantifying characteristic information about a characteristic of each measurement point, other than spectral information of the measurement point and using the spectral information as an independent variable in the partial least squares regression; and a spectrum reconstruction step of reconstructing the multipoint spectral data for each measurement point to eliminate a component having an eigenvalue lower than a predetermined value, from the components determined in the PLS analysis step.
    • 一种噪声分量去除方法,用于从通过在样本表面的测量点执行的测量产生的多点频谱数据中去除噪声分量,所述方法包括:PLS分析步骤,用于确定每个测量点的多点频谱数据的分量 通过使用通过量化关于每个测量点的特性的特性信息获得的值而获得多点频谱数据进行多变量分析的多点分析数据,除了测量点的光谱信息以外,以及 在偏最小二乘回归中使用光谱信息作为独立变量; 以及频谱重构步骤,根据在PLS分析步骤中确定的分量,重构每个测量点的多点频谱数据以消除具有低于预定值的特征值的分量。

    • An input unit inputs respectively a plurality of partial images corresponding to a user to be authenticated. An extraction unit extracts feature points of a fingerprint respectively from the plurality of partial images inputted. A generation unit synthesizes the feature points extracted respectively from the plurality of partial images and then generates feature point information for authentication. An acquisition unit acquires reference feature point information. A rotation unit performs phase rotation on the generated authentication feature point information so that a directional component, namely, a phase component, contained in the generated authentication feature point information approaches that contained in the acquired reference feature point information. An authentication unit authenticates the authentication feature point information whose phase has been rotated, based on the reference feature point information.
    • 输入单元分别输入与要认证的用户对应的多个部分图像。 提取单元从输入的多个部分图像分别提取指纹的特征点。 生成单元合成从多个部分图像分别提取的特征点,然后生成用于认证的特征点信息。 采集单元获取参考特征点信息。 旋转单元对所生成的认证特征点信息执行相位旋转,使得包含在生成的认证特征点信息中的方向分量,即相位分量接近包含在所获取的参考特征点信息中。 认证单元基于参考特征点信息认证其相位旋转的认证特征点信息。
