Can I use some parameters with DeepSORT in DeepStream Tracker

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I am trying to use DeepSORT in nvtracker.

I read a document and found some parameters in state estimater module.

  • processNoiseVar4Loc
  • processNoiseVar4Size
  • processNoiseVar4Vel
  • measurementNoiseVar4Detector
  • noiseWeightVar4Loc
  • noiseWeightVar4Vel

And it looks that the document recommends that we should use “noseWeightVar4Loc” and “noiseWeightVar4Vel” for DeepSORT.
I would like to know what these are used for and do we have to use noiseWeightVar4Loc and noiseWeightVar4Vel instead of others (, more over can we use procesNoiseVar4Loc and so on with DeepSORT)?

Thank you.

@kesong

I appreciate for your support.

I’ve already read this section.
And I felt this section recommend me to use these settings blow instead of other configurations such as processNoiseVar4Loc and so on.

  • measurementNoiseVar4Detector
  • measurementNoiseVar4Tracker

Is there any problem to use ‘processNoiseVar4Loc’, ‘processNoiseVar4Size’, ‘processNoiseVar4Vel’ and ‘measurementNoiseVar4Detector’ with DeepSORT?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one.
Thanks

The reason why DeepSORT uses different params in Kalman filter than NvDCF is because we wanted to follow the same algo as in the original DeepSORT implementation. But, you are free to use the same Kalman filter params from NvDCF for DeepSORT.
