MapAnything is a unified feed-forward transformer that regresses metric 3D scene geometry and cameras from images using a factored representation of depth maps, ray maps, poses, and scale.
A zero-shot subject-driven video generation framework that decomposes the task into identity injection from 200K subject-image pairs and motion preservation from 4K arbitrary videos, trained in 288 A100 GPU hours on CogVideoX-5B to match prior performance at 1% compute.
