SynSin: End-to-end View Synthesis from a Single Image (CVPR 2020)

This is the code for the CVPR 2020 paper. This code allows for synthesising of new views of a scene given a single image of an unseen scene at test time. It is trained with pairs of views in a self-supervised fashion. It is trained end to end, using GAN techniques and a new differentiable point cloud renderer. At test time, a single image of an unseen scene is input to the model from which new views are generated.

**Fig 1: Generated images at new viewpoints using SynSin.** Given the first image in the video, the model generates all subsequent images along the trajectory. The same model is used for all reconstructions. The scenes were not seen at train time.

Usage

Note that this repository is a large refactoring of the original code to allow for public release and to integrate with pytorch3d. Hence the models/datasets are not necessarily the same as that in the paper, as we cannot release the saved test images we used. To compare results, we recommend comparing against the numbers and models in this repo for fair comparison and reproducibility.
