Abstract
Biometric data are obtained through a biometric input device () and subsequently pixelated via a pixelator (). The pixelator () creates an image of the biometric data. Via a processing unit (), 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 () or compared with previously stored feature values for validation of the biometric data.
