Verification Performance : ROC


The table shows for each institution and study the so-called equal error rate which is a quantity derived from the receiver operating characteristic. The equal error rate is obtained when the false accept rate (fraction of all people erroneously allowed into a building) equals the false reject rate (i.e. fraction of legitimate people who are denied access erroneously). as a gif image.
