Overview
- Easi3R extracts 3D motion from videos without any training
- Builds on DUSt3R to disentangle camera movement from object motion
- Uses geometric constraints and point matching across frames
- Achieves competitive results without needing labeled data
- Works with complex real-world scenes including multiple moving objects
Plain English Explanation
Easi3R is a clever approach that figures out what's moving in videos without needing to train on massive datasets. It builds on another system called DUSt3R that already creates 3D sc...
