I find the value of tracker-width and tracker-height affect the result of tracking when I use IoU tracker.
are the objects bbox resized to [tracker-width, tracker-height] when use IoU tracker ?
In my mind, I think calculation of IoU is based on bbox detected, don’t need to resize.

No, it’s the frame width/height
Refer Gst-nvtracker — DeepStream 5.1 Release documentation

Does that means, in tracker part the input frame (for example: 1920 x 1080) will be resized to (tracker-width, tracker-height) for example (640, 384), and the bboxes will be resized correspondingly ?

Yeah, exactly.
