    • Biometric data are obtained through a biometric input device (120) and subsequently pixelated via a pixelator (130). The pixelator (130) creates an image of the biometric data. Via a processing unit (110), a relationship between pixels of a transformed version of the image is asserted. Thus, the biometric data is rotated to a consistent inclination based on the relationship between pixels regardless of an orientation in which the biometric data were captured in the original image. Once the image has been transformed, features of the biometric data may be extracted and either stored in a data storage unit (140) or compared with previously stored feature values for validation of the biometric data.
    • 通过生物特征输入装置(120)获得生物特征数据,随后经由像素(130)进行像素化。 像素化器(130)创建生物特征数据的图像。 通过处理单元(110),断言图像的变换版本的像素之间的关系。 因此,生物特征数据基于像素之间的关系而旋转到一致的倾斜度,而与生物特征数据在原始图像中捕获的取向无关。 一旦图像被变换,生物特征数据的特征可以被提取并存储在数据存储单元(140)中,或者与之前存储的特征值进行比较以验证生物特征数据。
