Stylizing-3D-Scene

PyTorch implementaton of our WACV 2022 paper "Stylizing 3D Scene via Implicit Representation and HyperNetwork". You can visit our project website here.

In this work, we aim to address the 3D scene stylization problem - generating stylized images of the scene at arbitrary novel view angles.

Our code is based on NeRF++: Analyzing and Improving Neural Radiance Fields.
The implementation of Hypternetwork and Style-VAE are based on Scene Representation Networks: Continuous 3D-Structure-Aware Neural Scene Representations and Adversarial Style Mining for One-Shot Unsupervised Domain Adaptation.
The implementation of Consistency metric(Temporal Warping Error) is borrowed from Learning Blind Video Temporal Consistency.
