According to the Deepsort paper (, the performance was excellent when only re-id was used (lambda=0, Except for Kalman), So can I use only re-id with Kalman motion turned off?

Here is the Data Association used in DeepStream DEEPSORT tracker:

Thank you for your answer
But I don’t think that’s a clear answer. There’s no place to turn off a score about Kalman Motion anywhere.

Can you check config_tracker_NvDeepSORT.yml in your system? I am not sure if stateEstimatorType = DUMMY is what you need.

Apart from what you said, DeepSort tracking_confidence metadata basically comes out to 1 always…

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.

Are you running deepstream-app? Can you share the reproduce step?
