What's the working strategy for secondary-gie when using nvDCF

What’s the working principle for secondary-gie when using nvDCF and primary-gie with interval greater than 0?

I am using nvDCF with a primary-gie which has inference interval greater than 0. As far as I know, for the frames skipped by primary-gie, nvDCF will predict the bbox using previous bbox result. But I dont know if the secondary-gie also works on those skipping frames. It is hard to tell from what I am testing.

Is there any source code about this procedure?

Could you share your setup with us?

SGIE will infer based on the bbox detected from PGIE

I have figured it out. Thanks
