When we are playing the sample deepstream-test2, we got two questions:
- Is tracker needed for secondary classifiers to work?
By default: pgie → tracker → sgie1 → sgie2 → sgie3, we did see the vehicle make, color, type classifier information plot on the video when running on video stream/sample_720p.h264.
If we remove tracker: pgie → sgie1 → sgie2 → sgie3, then all the sgie info are gone.
I am wondering if sgie1/2/3 only works on ROIs that from tracker?
- How to force the classifier always output a label?
Also on deepstream-test2, we saw vehicle make/type/color are missing from time to time. I tried to lower the
classifier-threshold=0, but it didn’t help much. So wondering other than this, is there any other thresholds or condition to meet for classifier?
Thanks a lot.
