Threshold of Primary detector

I am working with a custom detector as the primary model.

Issue - Object is being detected with a threshold as 0.01 but not being detected with a threshold as 0.001.
So, this confuses me, as per documentation the behaviour is ironic.

Please help me with the following

  1. What else parameters can I tune to get better results?
  2. What is the reason behind this? Is this any bug, or any issues from the model?
  3. What is the range of the threshold parameter? Is it from (0,1)?

Thanks in advance!.

Have you checked the raw model output?

Raw model output, I am not sure?

I get two matrices as output, one as bboxes and confidence scores and I filter them using the threshold parameter.

Per your description, you are using a custom detector, so I think you need to check the raw model(your detector ) output to see if the confidence meet your target
