Confidence in OpenCV FaceRecognizer predict method output
<p>I am using OpenCV for face recognition and have a newbie question.
Here is a portion of my code:</p>

<pre><code>recognizer = cv2.createLBPHFaceRecognizer()
...
nbr_predicted, confidence = recognizer.predict(predict_image)
...
</code></pre>

<p>My question is the higher the <strong>confidence</strong> is means faces are more similar or less similar?</p>
