We present a novel method for performing flexible, 3D-aware image content<br>manipulation while enabling high-quality novel view synthesis. While NeRF-based<br>approaches are effective for novel view synthesis, such models memorize the<br>radiance for every point in a scene within a neural network. Since these models<br>are scene-specific and lack a 3D scene representation, classical editing such<br>as shape manipulation, or combining scenes is not possible. Hence, editing and<br>combining NeRF-based scenes has not been demonstrated. With the aim of<br>obtaining interpretable and controllable scene representations, our model<br>couples learnt scene-specific feature volumes with a scene agnostic neural<br>rendering network. With this hybrid representation, we decouple neural<br>rendering from scene-specific geometry and appearance. We can generalize to<br>novel scenes by optimizing only the scene-specific 3D feature representation,<br>while keeping the parameters of the rendering network fixed. The rendering<br>function learnt during the initial training stage can thus be easily applied to<br>new scenes, making our approach more flexible. More importantly, since the<br>feature volumes are independent of the rendering model, we can manipulate and<br>combine scenes by editing their corresponding feature volumes. The edited<br>volume can then be plugged into the rendering model to synthesize high-quality<br>novel views. We demonstrate various scene manipulations, including mixing<br>scenes, deforming objects and inserting objects into scenes, while still<br>producing photo-realistic results.<br>
