Temporal Interpolation Is All You Need for Dynamic Neural Radiance Fields

no code implementations CVPR 2023 Sungheon Park, Minjung Son, Seokhwan Jang, Young Chun Ahn, Ji-Yeon Kim, Nahyup Kang

Despite the simplicity of the model architectures, our method achieved state-of-the-art performance both in rendering quality for the neural representation and in training speed for the grid representation.

PANeRF: Pseudo-view Augmentation for Improved Neural Radiance Fields Based on Few-shot Inputs

no code implementations23 Nov 2022 Young Chun Ahn, Seokhwan Jang, Sungheon Park, Ji-Yeon Kim, Nahyup Kang

To overcome this challenge, we propose pseudo-view augmentation of NeRF, a scheme that expands a sufficient amount of data by considering the geometry of few-shot inputs.

Procrustean Regression Networks: Learning 3D Structure of Non-Rigid Objects from 2D Annotations

no code implementations ECCV 2020 Sungheon Park, Minsik Lee, Nojun Kwak

We propose a novel framework for training neural networks which is capable of learning 3D information of non-rigid objects when only 2D annotations are available as ground truths.
