Abstract: A method for level three feature extraction from a print image extracts features associated with a selected ridge segment using a gray-level image under the guidance of at least one binary image. The level three features are a sequence of vectors each corresponding to a different level three characteristic and each representing a sequence of values at selected points on a print image. The level three features are stored and used for level three matching of two prints. During the matching stage, ridge segments are correlated against each other by shifting or a dynamic programming method to determine a measure of similarity between the print images.

Abstract: Print image processing includes generating a first direction image and a multi-resolution hierarchy tree (MRT) having a plurality of direction measures, and adjusting at least one direction measure based on whether it is associated with a singularity area or a non-singularity area of the MRT, to output a final first direction image used for further print image processing. The MRT direction images include the first direction image having a highest resolution and at least one other direction image having a lower resolution. Each direction measure is determined from a direction measure, in a higher resolution direction image, which is selected based on image quality and distance from the boundary between print areas and non-print areas. Upon determining the final first direction image, a consistency measure can be computed and compared to a consistency metric and the method iteratively performed until the consistency measure satisfies the consistency metric.
