Can someone explain to me basically how the confidence is calculated in the Eigenfaces, LBPH and Fisherfaces methods from the OpenCV Contrib modules? Is it calculated based on the distance?

Thanks in advance

yes, it is the distance between your query image and the closest in the train set, chi-sqr dist for lbph, and L2 (euclidean) dist for eigen & fisher

(and don't get fooled by the name "confidence", it 's rather the opposite, so smaller==better !)

Thanks a lot @berak.
