The Anytrack method allows us to identify and track specific points of interest (like animal limbs or facial features) across video frames with minimal manual labeling. By using just a few cameras, not necessarily professional or precisely positioned, and a small amount of initial manually labeled data, can understand and recreate the 3D structure of moving subjects.

• Revolutionary 3D Modeling with Minimal Setup: Achieve high-fidelity 3D modeling with just a few uncalibrated cameras using MV-NRSfM technology.
• Outlier Detection and Denoising Made Easy: Automatically clean and refine data with our approach that exploits shape variation redundancy for accurate 2D landmark estimates.
• Innovative Label Propagation for Efficient Data Annotation: Dramatically reduce manual labeling efforts with advanced deep optical flow, streamlining the semi-supervision process.

AnyTrack significantly reduces the need for extensive human labor traditionally required for accurate video annotation. It's particularly effective for capturing and analyzing the movement of various animals and humans in natural settings, making it a powerful tool for research across entertainment, biology, and more.
