How to configure ReID model for a specific object class in config tracker?

Hello,

Assume

  • A detection model that can detect person and car

I would like nvtracker (NvDCF) to track both types of objects (person and car), and I would like to configure ReID model for person class only.

Looking at the config_tracker_NvDCF_accuracy.yml, there is no option for configuring this. So it assumes ReID model will be applied for both types of objects?

If you have any hint, please help us?

I will check internally and feedback. Can you ignore the ReID vector of car currently?

Thanks for considering it.

So far, I have configured NvDCF not to use ReID model. I use a SGIE to extract person embeddings and then these embeddings are sent to a message broker (Kafka). Another service will obtain messages from that broker.

However, I still prefer “configuring ReID model for person class only.” in config_tracker_NvDCF_accuracy.yml.

Dear @kesong ,
Is there any update on this feature?

I have checked DS_plugin_gst-nvtracker, I see the params of the config_tracker_NvDCF_accuracy.yml.

If we track very different objects such ash players and the balls (small and moving very fast), if the tracking params could be configured for object, it would be much convenient. Please consider putting this feature in the roadmap. Thank you so much.
