From nvdsmeta.h where it states “For objects found by a tracker and not inference component, confidence will be set to -0.1”
Would it be possible to change this such that the parameter contains the value from the last component to process confidence?.
If an IOU or KTL Tracker comes after the inference, to somehow carry the confidence value between frames that were inferred on? Perhaps this is a IOU and KTL update?
The challenge with the current solution is… if a client is making decisions in a Pad Probe callback based on confidence levels – i.e. shade the background of the object with the highest confidence – , then the client has to carry this information forward between inferred on frames.
It seems that it would be a lot easier if the Plugin did this instead
If the handler is making decisions based on the confidence value – shading the background of the object with highest confidence as a simple example – how does the handler deal with the missing data?
The only way that I can think of solving this is to have the handler track each of the objects by tracker id, replacing the -0.1 with the last know confidence value… which is not a trivial task.
It just seems like the KTL and IOU Tracker, already tracking the objects, could do the above instead of adding the -0.1. The inferred on flag lets the client know if it came from the GIE or Tracker,
