**• Question

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

Where can we get the default values of the tracker configuration parameters?

#3

Default values are:

m_useUniqueID = true;
m_maxTargetsPerStream = 99; 

m_useHog = true;
m_useColorNames = true;
m_useHighPrecisionFeature = true;
m_featureFocusOffsetFactor_y = 0.0f;

m_filterLr = 0.15;
m_gaussianSigma = 0.75f;
m_peakCorrLr = 0.1f;
m_lambda = 5.f / 100.0f;
m_featureImgSize = 72;

m_SearchRegionPaddingScale = 1;
m_modelMaskingWindowFactor = 2;

The actual parameter should be tuned according to the actual video content.

Great, many thanks Fiona!

#5

Fiona, would you have the yml version of this?

#6

Fiona, would you have the default values for DS 5.0? Thanks and regards

#7

NO.

There is no change of default values from DS5.0 to DS5.1

#8

Fiona,

thanks for your feedback. However the list of parameters that you sent is not fully in line with the list of parameters on the tracker_config.yml that is coming with the isntallation of DS 5.1. As an example, on the tracker_config.yml we have featureImgSizeLevel, but this parameter is not on your list. Like this, there are some other cases for which I do not know what is the default value.

Thanks again for your support and best regards

Some of the parameters are reserved, you can not config and change them.

ok, thanks
