WebThe probability of false alarm expresses the event that a ‘no-defect’ pixel can be classified as a ‘defect’ pixel. In the PL case, we obtained the following results: Pd = 65% and Pfa = … WebROC curves are used in clinical biochemistry to choose the most appropriate cut-off for a test. The best cut-off has the highest true positive rate together with the lowest false positive rate. As the area under an ROC curve is a measure of the usefulness of a test in general, where a greater area means a more useful test, the areas under ROC ...
