MATCHING METHODS AND APPARATUS USING LANDMARK POINTS IN A PRINT |
摘要 |
A method for comparing a search print to a plurality of file prints includes performing a gray scale-based matching process, wherein cross-section profile pairs are determined between minutiae and landmark points in a search print and corresponding respondent prints, and individual similarity measures are computed based on the cross-section profile pairs using an elastic correlation process. A composite similarity measure is computed from the individual similarity measures. Optimizations such as segment outlier optimization (to eliminate outlier segments/minutiae points from the composite similarity measure computation) and adjusting the landmark point location in the search or respondent print can be implemented to maximize the composite similarity measure for a given respondent print. This maximized composite similarity measure can be combined with a similarity measure from another print matcher such as another gray scale-based matcher.
