Documentation>MATLAB API>PLOTOP - vl_det

[MISSRATE, FALSEALRAM] = VL_DET(LABELS, SCORES) computes the Detection Error Trade-off (DET) curve for the given set LABELS and SCORES. The function is a simple wrapper to VL_ROC(LABELS, SCORES). In fact, MISSRATE is simply the false positive rate and FALSEARALM the false negative rate returned by VL_ROC().

VL_DET(...) without output arguments plots the curves in the current axis. Note that the DET curves use logarithmic axis.

VL_DET(..., OPT, ARG, ...) accepts the same options as VL_ROC().
