Recognition Confidence
What is the number mean for the Confidence? for example: Eigen_model->predict(face_resized, Eigen_Predict, Eigen_Confidence); and i have the same for LBPH and Fisher algorithms.
I would like to know this to get more accurate predictions because each algorithm is giving me different predictions and none are the correct predictions either.
also here is my project with full code on github.com https://github.com/Chochstr/OpenCVapp/
if you set the threshold to 0.0, it will discard all neighbours, and return -1 all the time
