Abstract

A system for converting an image-enhanced digitized raster fingerprint image to vector lines in order to generate a unique identification value for the fingerprint. The raster image pixels are converted to vector lines along the fingerprint ridges and the vector lines are classified and converted according to type. The line types are then analyzed and a list of identification features corresponding to the vector line types is generated. The identification features between the vector line types are compared and the image is classified according to fingerprint class. A unique identification value is then generated by numerically encoding the classified identification features.
