Biometric process for digital print recognition, involves determining invariant centre from lines reproducing structure of print, on image of print to be recognized and centralizing print to be recognized as function of centre

摘要

The process involves determining an invariant centre from the lines reproducing the structure of a print, on the image/picture of the print to be recognized. The print to be recognized is centralized, as a function of the centre. The centre is then determined from the accumulated picture. The centre relates to a maximal value in the accumulated picture or a barycenter of the highest value in the accumulated image. An Independent claim is also included for a biometric device for recognition of digital print.
