detectMultiScale3 confidence range

Hello, I want to use the detectMultiScale3 function to get not only the bounding boxes of the detected faces, but also the level of certainty of each prediction. Does anyone know the range of this level of certainty, and if it would count as the confidence value needed to plot a PR curve? We have been using the function but the return values are quite low, and they don’t seem to be a percentage.

Thanks for the help!

definitely not.

For each resulting detection, `levelWeights` will then contain the certainty of classification at the final stage.
