How important is real-time point tracking?
Cubsat "HORIZON" in PointTracking mode for our Mission Control Center made several images and sent them to Earth. A rope, which used to hold the antennas, but is now in the drift.
🚀Introducing Protracker: Inspired by Kalman filter, we tackle point tracking with a robust probabilistic approach.
🌟Our method integrates multiple predictions from both optical flow and semantic correspondences in a unified framework with probabilistic fusion. This ensures to generate smooth and accurate trajectories. ProTracker achieves state-of-the-art performance among self-supervised methods across multiple benchmarks and enhanced robustness in challenging scenarios like occlusion, similar regions, and low-feature areas.
💡Protracker offers a probabilistic framework that combines information of different granularity and semantics, paving the way for new advancements in tracking any point.

COTRACKER3: SIMPLER AND BETTER POINT TRACKING BY PSEUDO-LABELLING REAL VIDEOS:
Meta's CoTracker3 simplifies the process of tracking points across videos by using a streamlined architecture and an efficient pseudo-labelling approach with minimal data.
Key Highlights:
✅ Data Efficiency: With only 15k real videos, CoTracker3 achieves state-of-the-art results, even outperforming models like BootsTAPIR, which used 15 million videos! This model is proof that efficiency in design can deliver exceptional performance.
✅ Handling Occlusions with Ease: Using cross-track attention, CoTracker3 accurately predicts the locations of occluded points based on visible ones, making it especially powerful in complex tracking scenarios.
✅ Self-Training Advantage: CoTracker3 fine-tunes on its own predictions, gaining an impressive performance boost ( 1.2 points on TAP-Vid benchmarks) and reducing the gap between synthetic and real-world data.
✅ Top Speed and Efficiency: CoTracker3 processes frames 30% faster than LocoTrack, the previous speed leader, while maintaining high accuracy—even with large numbers of tracked points.
✅ Scalability with Minimal Data: Its performance scales effectively with just a moderate increase in training data (up to 30k videos), showing excellent balance in training requirements without compromising results.
✅ The authors also discuss some failure cases, providing insights into areas where CoTracker3 could improve further.
This model has exciting applications in areas like 3D tracking, real-time video analysis, and dynamic 3D reconstruction.
