“…Later, Wu et al [92] extended this approach, conditioning predictions on the trajectories of objects that their model segments and tracks. Recent work has used other motion representations, such as factorizing a scene into stationary and moving components [12,85,83], per-pixel kernels [24,86,64,70,47], or Eulerian motion [55]. Work in 3D view synthesis has adopted a similar copy-and-paste approach, known as appearance flow [102,66,66].…”
