BootsTAP: Bootstrapped Training for Tracking-Any-Point

Doersch, Carl, Luc, Pauline, Yang, Yi et al.

Understand

To endow models with greater understanding of physics and motion, it is useful to enable them to perceive how solid surfaces move and deform in real scenes.

  • This can be formalized as Tracking-Any-Point (TAP), which requires the algorithm to track any point on solid surfaces in a video, potentially densely in space and time.
  • Large-scale groundtruth training data for TAP is only available in simulation, which currently has a limited variety of objects and motion.
  • In this work, we demonstrate how large-scale, unlabeled, uncurated real-world data can improve a TAP model with minimal architectural changes, using a selfsupervised student-teacher setup.
