Unconstrained Face Recognition with User Interaction

Face recognition in unconstrained environment is very challenging due to the variations in facial expression, face pose, light condition and occlusion (e.g. eye glasses or hair). A recent project led by Dr. Learned-Miller at University of Massachusetts, Amherst, published the test results on 13,000 images of faces collected from web. The results are described in an ROC curve. At 10% false positive rate, the best true position rate (recognition rate) is around 67%. That is, in 100 face images for one person, only 67 faces are correctly recognized as this person; in 100 faces images of other persons, 10 faces are incorrectly recognized as this person. Therefore there is still big gap between this performance and the requirements of security applications, for example, access control. But are these results useful for other practical applications?
