Abstract:
1. A method of candidate identification utilizing fingerprint identification, the method comprising: receiving a candidate comprising a plurality of pixels arranged on a background; identifying at least two subsets of the plurality of pixels where each pixel in a subset is within a threshold distance of at least one other pixel in the subset and wherein each pixel within one subset is not within the threshold distance of any pixel of any other of the at least two subsets; determining one representative pixel for each of the identified at least two subsets; building a candidate fingerprint of the candidate based on the determined representative pixels and not on the remaining pixels of each of the at least two subsets; comparing the candidate fingerprint to a plurality of exemplar fingerprints, each corresponding to one of a plurality of exemplars and determining the best match there between; and identifying the candidate based on the exemplar corresponding to the exemplar fingerprint which best matches the candidate fingerprint.
