FaceRecognizer Confidence
I'm developing an OpenCV Face Recognition application in C++ in VisualStudio 2010. I've been using all three methods, but mostly leaning towards LBP. The point of the application is to compare percent similarity of images of faces to a specific face from a training set. Is there a way to turn the returned confidence value from the predict method into a percent value that makes sense? I know that these values correspond somewhat to a distance between faces, and a lower number corresponds (inversely) to a higher confidence level, but where does the actual number come from? I want to return a percent similarity for my application, but I'm not sure what the returned confidence means. Specifically, does anyone know anything about the confidence value pertaining to the LBP method? Does anyone know what the range of possible values for confidence are?
Thanks a bunch!
