## Tracking through occlusions

We track points sampled on the first frame. Please note that only CoTracker and RealTracker can track through occlusions.

However, CoTracker loses tracked points at the end while we are still tracking them.

## Object-centric tracking on a regular grid

We track 10k points sampled on a regular grid starting from the initial video frame.

Since the points are grid-sampled, tracks without significant transformations should maintain grid patterns in future frames.

LocoTrack and RealTracker tracks are better aligned than BootsTAPIR tracks. Neither LocoTrack nor BootsTAPIR can track through occlusions.

They also lose more background and object points than RealTracker.

## Before / after scaling; Online / offline models

Scaling helps improve both models, while in these examples the online model benefits from scaling more than the offline one.
