DUET4D: Self-Corrective Coupled Guidance for Sparse-View 4D Reconstruction

Sparse-view 4D reconstruction is highly under-constrained when only a few cameras are available. Generative priors can recover missing appearances, but video models are computationally impractical for iterative reconstruction, whereas single-view models produce temporally inconsistent pseudo-observations. Moreover, dir...
