First you populate the gallery with the recovered orientation of each face, so the gallery can be segmented by pose, and then the laborious process of humans evaluating the accuracy via generation of a ROC Curve for the gallery. Which can be segmented by face orientation to show the accuracy as orientation varies. People generally hate calculating these because it requires a human to evaluate the FR matches, and mental fatigue set in very quickly.
