Abstract:
1. A method of transforming an image of a biometric surface, comprising the steps of: sensing the biometric surface using a contact imaging device to provide sensed biometric image data having at least two rows and two columns and image parameters including at least image resolution; receiving transform data relating to a plurality of transform parameters including at least image resolution for use in transforming the sensed biometric image data, wherein different transform parameters result in differently transformed image data for a same biometric image data; transforming the sensed biometric image data in accordance with the received transform data to provide transformed biometric image data in a biometric imaging data format other than a biometric imaging data format of the sensed biometric image data; and providing the transformed biometric image data as output image data, wherein the transformed biometric image data is different for different transform parameters enabling provision of images of a same biometric surface having different biometric imaging data formats.
