Claim 13:
14. The system of claim 13, wherein the action of identifying the plurality of matching line-pair groups comprises:
for each line-pair from the first set of discriminative line-pairs which refers to a first line-pair,
comparing the line-pair feature vector of said first line-pair with respective line-pair feature vectors of line-pairs from the second set of discriminative line-pairs;
determining one or more line-pairs from the second set of discriminative line-pairs as a candidate of matching line-pairs to said line-pair if the line-pair feature vector of said first line-pair and the one or more line-pairs meet the at least one thresholding criterion; and
grouping said first line-pair and the candidate of matching line-pairs into a matching line-pair group, said first line-pair being the first discriminative line-pair and the candidate of matching line-pairs being the second discriminative line-pair.
