MAMMA tracks complex 3D motion with just 4 cameras
Researchers from Max Planck and CMU just open-sourced MAMMA, a markerless motion capture system that converts multi-view video into accurate 3D models with only four standard cameras. It tracks complex interactions like dancing and hugging without wearable sensors, easily pulling off Matrix-style bullet time effects. The code and a browser UI are available on GitHub for non-commercial research.
