Zero term tracking - correct description

[maxsitt]

In the DepthAI docs, Zero term tracking is described as:

...performs object association, which means that it does not conduct prediction and tracking based on previous tracking history.

In the Intel DL Streamer docs it is described as:

...based on comparing object coordinates on current frame with objects trajectory on previous frames.

Both descriptions seem to contradict themselves, I'm wondering what is correct?

From what I understood, the DepthAI object tracker types are basically the same as from the Intel DL Streamer framework/OpenVINO toolkit, is that correct?
