We propose StyleNeRF, a 3D-aware generative model for photo-realistic high-resolution image synthesis with high multi-view consistency, which can be trained on unstructured 2D images. Existing approaches either cannot synthesize images fine details or yield noticeable 3D-inconsistent artifacts. In addition, many of them lack control over style attributes and explicit 3D camera poses. StyleNeRF integrates the neural radiance field (NeRF) into style-based generator to tackle aforementioned...

We present a new neural representation, called Neural Ray (NeuRay), for the novel view synthesis task. Recent works construct radiance fields from image features of input views to render images, which enables generalization scenes. However, due occlusions, 3D point may be invisible some views. On such point, these methods will include inconsistent views, interfere with field construction. To solve this problem, we predict visibility points within our NeuRay representation. This construction...
