Hi
I am using deepstream 4.02. I observed that DCF not able to tracker a single person which moving inside the closed area.
Camera is put on ceiling and person is clearly visible. Person detection model output is satisfactory but tracking is not good.
Some time frequently ID get change in single person tracking. Some time tracker is not able to tracke a person standing for some time.
Below the configuration that I used for DCF
%YAML:1.0
NvDCF:
maxTargetsPerStream: 30 # Max number of targets to track per stream. Recommended to set >10. Note: this value should account for the targets being tracked in shadow mode as well. Max value depends on the GPU memory capacity
filterLr: 0.1 # learning rate for DCF filter in exponential moving average. Valid Range: [0.0, 1.0]
gaussianSigma: 0.75 # Standard deviation for Gaussian for desired response when creating DCF filter
minDetectorConfidence: 0.4 # If the confidence of a detector bbox is lower than this, then it won’t be considered for tracking
minTrackerConfidence: 0.6 # If the confidence of an object tracker is lower than this on the fly, then it will be tracked in shadow mode. Valid Range: [0.0, 1.0]
featureImgSizeLevel: 5 # Size of a feature image. Valid range: {1, 2, 3, 4, 5}, from the smallest to the largest
SearchRegionPaddingScale: 3 # Search region size. Determines how large the search region should be scaled from the target bbox. Valid range: {1, 2, 3}, from the smallest to the largest
maxShadowTrackingAge: 24 # Max length of shadow tracking (the shadow tracking age is incremented when (1) there’s detector input yet no match or (2) tracker confidence is lower than minTrackerConfidence). Once reached, the tracker will be terminated.
probationAge: 2 # Once the tracker age (incremented at every frame) reaches this, the tracker is considered to be valid
earlyTerminationAge: 4 # Early termination age (in terms of shadow tracking age) during the probation period
minVisibiilty4Tracking: 0.2 # If the visibility of the bbox of a tracker gets lower, then it will be terminated
could you suggest the best tuned parameters based on your experience?
