Hi AndrzejFijalo
AndrzejFijalo Does the ZERO_TERM_COLOR_HISTOGRAM tracker type provide some tracking information between detection instances? To elaborate, if I have 3 consecutive frames and an object is detected in the first and third frames, does the tracker give ROI information in the second frame?
Yes, the type will provide tracking information in case the object cannot be found.
AndrzejFijalo When does the Tracker set the object status as LOST? Is it when it doesn't get object coordinates from the detector, or are there some other conditions?
The status is set to of as soon as the NN node is not passing it any detections.
AndrzejFijalo How many frames pass between the LOST and REMOVED statuses?
In my experience the upper limit is 120 frames. After that, the status will be set to removed. But if the tracker's algorithm predicts the objects (which was tracked before, but is lost now) trajectory would have taken the object out of frame, the status will prematurely be set to removed.
Thanks,
Jaka
