Real-time Free-view Human Rendering from Sparse-view RGB Videos using Double Unprojected Textures

Inputs Output Ground Truth IND Inputs Output Ground Truth OOD Figure 1. We propose Double Unprojected Textures (DUT), a new method to synthesize photoreal 4K novel-view renderings in realtime. Our method consistently beats baseline approaches [32, 38, 52, 59] in terms of rendering quality and inference speed. Moreover, it generalizes to, both, in-distribution (IND) motions, i.e. dancing, and out-of-distribution (OOD) motions, i.e. standing long jump.
