Abstract (in Japanese) (See Japanese page) 
(in English) Neural Radiance Fields (NeRF) is a powerful method for novel view synthesis.
However, NeRF requires a large number of images for training.
In this paper, we propose the Manifold NeRF, which uses the interpolated feature from neighboring viewpoints as pseudo ground truth at each unknown viewpoint for its training in addition to the original NeRF loss for known viewpoints.
As a result of the experiments, we confirmed that the interpolated pseudo ground truth helps training of NeRF with a limited number of images.
