Neural Free-Viewpoint Relighting for Glossy Indirect Illumination

no code implementations12 Jul 2023 Nithin Raghavan, Yan Xiao, Kai-En Lin, Tiancheng Sun, Sai Bi, Zexiang Xu, Tzu-Mao Li, Ravi Ramamoorthi

In this paper, we demonstrate a hybrid neural-wavelet PRT solution to high-frequency indirect illumination, including glossy reflection, for relighting with changing view.

Sim2Real for Self-Supervised Monocular Depth and Segmentation

1 code implementation1 Dec 2020 Nithin Raghavan, Punarjay Chakravarty, Shubham Shrivastava

Image-based learning methods for autonomous vehicle perception tasks require large quantities of labelled, real data in order to properly train without overfitting, which can often be incredibly costly.
