AllTracker: Efficient Dense Point Tracking at High Resolution

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)?

Back in my earlier days working on autonomous vehicles, I dreamed of something like this.

The issue with bounding boxes is missed detections, occlusions, and impoverished geometrical information. But if you have a hundred points being stably tracked on an object, it's now much easier to keep tracking it through partial occlusions, figure out its 3D geometry and kinematics, and even re-identify it coming in and out of occlusion.

No, this performs the same task as CoTracker or TAPIR, but intended for running at a higher resolution. Point tracking is useful both for keeping track of the position of a target and for "inside-out" positioning of the camera.

YOLO is mostly concerned with detecting objects of certain classes in a single image, and SAM is concerned with essentially classifying pixels as belonging to an object or not.

Using optical flow for point tracking is obvious, not that the goal of tracking pixels is obvious.

Regarding your actual question, there's many use cases.

- Tracking players or balls in sports

- Surveillance

It takes freshly deployed humans a while to master, and only then with fairly high bandwidth training data, so I wouldn’t feel too bad about the complexity of implementing it in software.
