DeepStream 6.2 default tracking is better than others

**• Hardware Platform (GPU) RTX 3060
**• DeepStream Version 6.2
• TensorRT Version
**• NVIDIA GPU Driver Version (valid for GPU only) CUDA12.0
• Issue Type (questions)

We have been running the deepstream-app with no tracker file (tracker_config.yml). On the command line we get the following warning:
!!![WARNING] Can’t open config file …tracker_config.yml). Will go ahead with default values

1.Where can we get the default values of the tracker configuration parameters on deepstream 6.2?
2.I have tested the following trackers and found that the default settings (The default value used when the above error occurs) are better than other trackers. Why?
config_tracker_IOU.yml
config_tracker_NvDCF_perf.yml
config_tracker_NvDCF_accuracy.yml
config_tracker_NvDCF_max_perf.yml
config_tracker_DeepSORT.yml

Here is the document for nvtracker. There are the default values: Gst-nvtracker — DeepStream 6.3 Release documentation

Can you share some video to show the result of “better”?

I’m sorry, I can’t provide videos due to limitations, but the main scenario is a car facing the opposite direction waiting at a red light. When a car passes by laterally, there is a 0.5-second interval of obstruction, during which the vehicle ID might be reassigned. Surprisingly, it’s the default tracker that can continue tracking during this moment.

config_tracker_NvDCF_accuracy.yml is the most accurate tracker. Please use this configure for accurate tracker.

You can share video with private channel if you want to check why there is tracker ID switch.
