issues with objectTracker

Thor

using any ZERO_TERM_COLOR_HISTOGRAM, ZERO_TERM_IMAGELESS, SHORT_TERM_IMAGELESS (SHORT_TERM_KCF cannot be used as it reduces fps by an order of magnitude), the tracker sometimes starts extending trajectories at a certain location/direction of an object,
creating two objects one of which is non real. See attached
Is there a way to tune the objectTracker parameters a little, to reduce the issue?

Hi Thor
Sorry, but I'm not really sure what I'm looking at.

Thor

I apologise for not providing more background info. Red dots are a representation of bboxes over time (a trajectory)
Top Image: Object is pretty much stationary. The objectTracker creates fake new objects that move in the shown 4 directions
Bottom image: vertical dots on straight line are a representation of the fake objects that objectTracker creates from an object that has changed direction

If possible we'd like to know if there is a parameter to reduces the look ahead behaviour of objectTracker that I assume is based on previous trajectory, but is too sensitive and believes to see the object when there is none (having lost tracking on the real one)

Also, the same behaviour is shown with either the short term and zero term initialisation values

Hi Thor
There is currently no parameters (apart from the tracking type) you can set. The issue seems to be your NN detection. There are a lot of frames in which the object is not being detected.

Thanks,
Jaka
