Min score ignored? False positives

[thomasfals]

Hi
I'm struggling with a lot of false positives. I have set min_score but still get detections that are below both min_score and threshold. What is wrong with my config?

Last night I got an alarm trigger for a "person" at 51% score.

Need to see an example of detections below the min score

[thomasfals]

This was scored as person with 51%

But is the point of the min score not to discard this totally? In my case I set min score to 0.75

[NickM-27]

how do you know it scored as 51%? if you have object metadata it would be great to see all of it

[thomasfals]

Where would I find this metadata? It does not appear to be readily available in the interface.

[NickM-27]

Right, it is readily available in the next version of Frigate.
