a question about score value in PredictionsTextFile export about norfair

I think everything else is exactly the same

Thanks! @aguscas you may have some insight on this.

Hello there! We are not using the confidence score of the detections during the evaluations. If you set that score to be anything greater or equal to -1, the evaluation will return the same results. If you set it to something less than -1, that specific prediction will be ignored during the evaluation. What I mean is that, it doesn't really matter to which number you set that confidence value, as long as it is greater or equal to -1

@aguscas thanks for your response!

In this comment you mentioned that when score is 0, that detection will be ignored during evaluation: #42 (comment).

That got me a bit confused. Are detections with score of 0 ignored or only detections with -1 are being ignored?

[aguscas]

If you set to 0 the confidence in your ground truth files, then that object will be ignored. So there are 2 confidence values, one thing is the confidence value in your trackers (which we set to -1), and another thing is the confidence value in the ground truth labels (which is set to 1 when you want to take that object into account in the evaluation, or 0 otherwise).

@aguscas thanks a lot, that clears all things up!

One last question. Are there any more differences between tracker output and ground truth or is this all i need to know while arranging ground truths and tracker outputs?

Thanks @aguscas for the help, we definitely need to do a better job at documenting some parts of this :)
