> 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]?

Object segmentation and tracking is such a natural and 'automatic' part of our visual perception that it's difficult to intuit how challenging it is to do with software. | ||||||||||||||||||||||||||||||||||||||||||||
