“…This test suite comprised 1,050 images without contaminations, 500 images of these non-contamination images were used to calculate the likelihood and the prior probability, and 313 images with contaminations which were used to calculated the likelihood and the prior probability. The results were compared to those reported in [5] where angle measurement and intensity were used to identify contamination in ABS images. We also report the results when 1) the proposed method used the likelihood, the prior probability and angle measurement without template registration, 2) the proposed method used only the likelihood without template registration, and 3) the proposed method used the likelihood and angle detection method with template registration.…”
