> The utility of optical flow (i.e., the instantaneous velocity of pixels [16]) toward this goal has long been obvious, yet it has remained challenging to upgrade flows into long-range tracks.

This sentence from the paper makes me feel a little bad that I don't understand why this goal is obvious. I am not tracking why we are tracking pixels.

Is this basically a competing technology with YOLO[1] or SAM[2]?

Edit: added annotations, should've done that initially

I’m not remotely familiar with either YOLO or SAM, but want to add my own question here. Does the utility of this invention have something to do with the tracking of subjects, like auto-focus for cameras and robotics (to keep the subject in view)?
