  1. This table summarizes the results for LAE, NCC and NCC-BB comparison methods in pattern tests. All three methods successfully detected the correct reference image. Please note that LAE measures dissimilarity, while NCC and NCC-BB measure similarity, hence the correct image has the lowest score under LAE, highest score under NCC and the score closest to 0 under NCC-BB method.
