when I change my precision from init8 to fp16 || 32, tracker id is stable but bounding box jitters a lot, how do we fix it?
Hi,
Could you share us a video for the issue you mentioned?
So we can check it with our internal team for some suggestion.
Thanks.
Hi AastaLLL,
Thanks
Hi,
We want to reproduce this issue in our environment.
Would you mind to share your platform and configuration with us?
Thanks.
Hi AastaLLL,
I am using
AGX, 24 * 1920 *1080(H.264/High Profile) @ 60 FPS, bitrate 47,195kbps. 1 detector and 3 classifiers
I have offloaded 3 classifiers to DLA 0 and 1
I have tried with H265 * 30FPS and I had a similar issue.
I am using KLT now
It would be best if you post your entire deepstream-app config file so we can reproduce. Are you inferencing at every frame?
@ i have shared privately[dm]
NvDcf does multi camera re-identification ?
If you still sees the issue when using KLT, pls try increasing tracker-width and tracker-height.
NvDCF and other trackers in DeepStream are all single-camera tracker.
KLT is stable but tracker id changes often this will be an issue in vehicle counting, how do we fix the jitter issue with nvdcf
Hi,
Could you modify the configure file based on our source30_1080p_dec_infer-resnet_tiled_display_int8.txt
We want to reproduce this issue in our environment first.
Thanks.
I am using modified source30_1080p_dec_infer-resnet_tiled_display_int8.txt, I have changed from int 8 to FP16
source30_1080p_dec_infer-resnet_tiled_display_int8.txt default config with NVDCF works fine, but its single-source video and a single detector
@AastaLLL we replicated the issue on 8 * AGX kits
Hello,
Thanks for your update.
We are investigating this issue internally.
Will update more information once we got any news.
Thanks.
Hi,

Hi Aasta,
Default demo runs fine with a single video
source30_1080p_dec_infer-resnet_tiled_display_int8.txt with singe source(video) works fine.
*source30_1080p_dec_infer-resnet_tiled_display_int8.txt has only 1 detector
Problem is only when we add multiple sources with different videos
I can give you VPN access to our lab
Can you try with
- Multiple video sources with different videos.
- Add secondary classifiers.

Hello Ravi,
I noticed that the PGIE interval is set to 4: interval=4 Can you reduce this to 2 or 1?
We found a bug in the release version of NvDCF, and it may cause such jitter in case of interval>0. We fixed it and the next release version will be much smoother.
Can you let me know what does interval mean in this context, does it mean the object detector running for 4 frames or of that sort?
Could you also specify where the documentation for config files are present?
Hi Pshin,
interval=0 is stable.
https://docs.nvidia.com/metropolis/deepstream/4.0/dev-guide/index.html#page/DeepStream_Development_Guide%2Fdeepstream_quick_start.html%23wwpID0E0GB0HA
We have a documentation at [DeepStream Development Guide]
Please refer to interval at PGIE section.
I cannot disclose any future plans, sorry. Please refer to a public announcement related to DeepStream. But, I guess we are trying to make the releases in a regular basis.
Hello @pshin, 6 months later I still experience the jitter issue described above with the nvdcf tracker that came with DeepStream 5.0DP if I set the interval parameter of the tracker to anything greater than zero. Do you have some update on the fix? Maybe we can patch the tracker somehow?
I created a small log that shows how many objects are tracked reported on the metadata stream for each from, running on the sample_720p.h264 example stream. I set interval=3 in the tracker config so the tracker should run only on each 4th frame. It is clearly visible that the number of objects reported is fluctuating: every 4th frame (I guess those ones when the tracker run) reports significantly more objects.
