Abstract:
1. A method of candidate identification utilizing fingerprint identification, the method comprising: receiving a candidate comprising content arranged in a content pattern comprising a plurality of pixels arranged on a background to form a plurality of constituent elements of the content, wherein the received candidate may correspond to one of a plurality of exemplars; compensating for rotation variation identified in the content pattern of the received candidate; 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 only on the determined representative pixels; comparing the candidate fingerprint to a plurality of exemplar fingerprints, each corresponding to one of the 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.
