I used peoplenet and nvdcf tracker, and I set 0.7 threshold confidence for person object, but it has one big problem, in some cases, scores of objects have negative, why? I set threshold 0.7.
and I set interval=0 for nvinfer.
Which confidence, I think following comments can explain that, refer NVIDIA DeepStream SDK API Reference: Main Page
Holds a confidence value for the object, set by the inference component.
confidence will be set to -0.1, if “Group Rectangles” mode of clustering is chosen since the algorithm does not preserve confidence values. Also, for objects found by tracker and not inference component, confidence will be set to -0.1
