Hi,

You can find the introduction of KLT algorithm below:

It assumes no lighting change, no foreground object and small motion.
If your scenario is different from the assumption, KLT may not work as expected.

In VPI, there are also some parameters you can play with:

Thanks for your support . Will next version VPI have more better trackers than like kcf, scrt,… ?. I hope you will add them in VPI

Hi,

Is Deepstream SDK an option for you?
We have implement KLT / IoU / DCF tracker within nvtracker.
