ViewFormer: NeRF-free Neural Rendering from Few Images Using Transformers. (arXiv:2203.10157v2 [cs.CV] UPDATED)

Novel view synthesis is a long-standing problem. In this work, we consider a
variant of the problem where we are given only a few context views sparsely
covering a scene or an object. The goal is to predict novel viewpoints in the
scene, which requires learning priors. The current state of the art is based on
Neural Radiance Field (NeRF), and while achieving impressive results, the
methods suffer from long training times as they require evaluating millions of
3D point …
