This function is used to set the threshold for the confidence (accuracy) of face detection, 0 being low confidence and 1 being high confidence.
With the threshold value, you can set the level of confidence required for face detection.
At 0.4 threshold:
At 0.9 threshold:
Tip: Use this block with a lower threshold if you are not able to detect objects due to dim light, partial appearance of the object, etc.
