Presentation attack detection algorithms are analogous to biometric matching algorithms in many ways. They are both used as classifiers, and their performance can be measured in terms of false positives and false negatives.

"A detection error tradeoff (DET) graph is a graphical plot of error rates for binary classification systems, plotting the false rejection rate vs. false acceptance rate. The x- and y-axes are scaled non-linearly by their standard normal deviates (or just by logarithmic transformation), yielding tradeoff curves that are more linear than ROC curves, and use most of the image area to highlight the differences … " - Detection error tradeoff det curve

WebIn a detection problem, the trade-off between the miss and false alarm probabilities are often shown as a Detection Error Trade-off (DET) curve. The DET curve i WebNov 1, 2016 · For rule-based systems, it can be described as the number of rules defining a classifier in proportion to the number of all possible rules. As it is easier to see the tradeoff between misclassification costs (i.e., fpr and fnr) when using DET space than when using ROC space, we use DET curve to describe the performance of binary classifiers.
