Abstract:
In some implementations, a method may be used for matching palm print images. A search template that identifies at least a plurality of distinctive search orientation blocks within a search orientation field may be initially generated for a search palm print image. A reference template may be obtained. A mated distinctive reference orientation block may be identified for each of the distinctive search orientation blocks. One or more regions of the search orientation field that include the distinctive search orientation blocks may be compared against one or more corresponding regions of the reference orientation field. An orientation similarity score between the search palm print image and the reference palm print image may be computed based on the comparison. A match may finally be determined if the computed orientation score satisfies a predetermined threshold value.

Claim (Index 7):
The method of  claim 1 , wherein:\n the obtained reference template identifies (i) a plurality of reference minutiae, and (ii) for each reference minutia, a corresponding reference octant feature vector; and the method further comprises:\n determining one or more transformation parameters between the search orientation field and the reference orientation field based at least on comparing one or more regions of the search orientation field and the one or more corresponding regions of the reference orientation field; \n aligning, using the one or more transformation parameters, the search palm print image to a coordinate system associated with the reference palm print image, the aligned search palm print image including an overlapping region between the aligned palm print image and the reference palm print image; \n identifying a plurality of search minutiae within the overlapping region of the aligned search palm print image; \n generating a search octant feature vector for each minutia within the identified plurality of search minutiae; \n identifying, for each generated search octant feature vector, a mated reference octant feature vector from among the plurality of reference octant feature vectors; \n comparing one or more features indicated by each search octant feature vector and one or more corresponding features indicated by each mated reference octant feature vector; and \n computing a match similarity score between the search palm print and the reference palm print based at least on comparing one or more features indicated by each search octant feature vector and one or more corresponding features indicated by each mated reference octant feature vector.
