SinNeRF: Training Neural Radiance Fields on Complex Scenes from a Single Image [article]

Dejia Xu, Yifan Jiang, Peihao Wang, Zhiwen Fan, Humphrey Shi, Zhangyang Wang
2022 arXiv   pre-print
In this work, we consider a more ambitious task: training neural radiance field, over realistically complex visual scenes, by "looking only once", i.e., using only a single view.  ...  Despite the rapid development of Neural Radiance Field (NeRF), the necessity of dense covers largely prohibits its wider applications.  ...  Fig. 1 : Given only a single reference view as input, our novel semi-supervised framework trains a neural radiance field effectively.  ...

2022 arXiv   pre-print
Neural Radiance Fields (NeRF) have emerged as a potent paradigm for representing scenes and synthesizing photo-realistic images.  ...  Furthermore, we show that a ray atlas pre-computed from the observed rays' viewing directions could further enhance the rendering quality for extrapolated views.  ...  A good practice is from Neural Radiance Fields (NeRF) [22] .  ...

In this context we investigate here the use of a neural radiance field view synthesis method, originally developed for its use with macroscopic scenes acquired with a moving (or an array of static) digital  ...  Therefore, it is important to have a tool for the generation of a high number of synthesized view images, without compromising their lateral resolution.  ...  In this sense, this paper presents, to the best of our knowledge, the first application of a neural radiance field-type method (NeRF--) for the synthesis of new views in FLMic.  ...
