HomeD4RT: Teaching AI to see the world in four dimensions
D4RT: Unified, efficient 4D reconstruction and tracking up to 300x faster than prior methods.
Meet D4RT, a unified AI model for 4D scene reconstruction and tracking. D4RT combines a powerful encoder that builds a rich, global understanding of the video, and a lightweight decoder that answers thousands of queries in parallel. By asking specific questions — identifying where a source pixel is located at a target time and camera view — the model efficiently solves diverse tasks like tracking, depth estimation, and pose estimation through a single, flexible interface.
