This code demonstrates how to compute GMAP metric. To generate the results use the following steps:
-
Place the comparison scores with FRS name subfolder for eg ComparisonScores\Arcface and ComparisonScores\VGGFace.
-
Generate FFMPMR and FTAR (Failure to Acquire Rate) for eg generateFFMPRValuesDatasetArcface and generateFFMPRValuesDatasetVGGFace.
-
Execute generateGMAPMetric to generate GMAP (Multiple Probe Attempts), GMAP (Multiple FRS and Multiple Probe Attempts) and GMAP. The regions are according to the paper (https://ieeexplore.ieee.org/document/10078862).
