AUC-Judd

• “location-based metric”
• The true positive rate (TPR) is calculated as the proportion of fixations falling into the thresholded saliency map
• The false positive rate (FPR) is calculated as the proportion of no-fixated pixels in the thresholded saliency map.
• After calculating TPR and FPR at each threshold, the area under the curve (AUC) is calculated for the curve of TPR against FPR.
