confidence of predict model (face recognizer) > 1
Hi, I am working on face Recognition (C++ code) in Android app.
In first, I use first findfaces() method to detect, resize each image of my person. It works well.
Then I want to recognize my face (via createEigenFaceRecognizer), I refer to sample images previously created, the image's path and the haarcascade_frontalface_alt.xml.The model is filled. I train the model. But as soon as model->predict(face_resized,prediction,predicted_confidence); is called, it returne me a confidence > 1. It is often between 1600 and 10000 depending on person. I do not understand why.
Yet, I have constructed my algorithm according to tutorial on openCV.
Can you help me ? I can give you my code.
Thanks in advance.
