Method

Figure 2 from SynSin Paper
  1. First a depth map and a set of features are generated for each pixel using depth network \(d\) and feature network \(f\).
  2. The depths are used to create a 3D point cloud of features \(P\).
  3. Features are repositioned using the transformation matrix T.
  4. Repositioned features are rendered using a neural point cloud renderer.
  5. Rendered features are passed through a refinement network \(g\).
