Introducing StyleGaussian: Instant 3D Style Transfer with Gaussian Splatting
Overview
StyleGaussian is an innovative 3D style transfer tool developed to enhance instant style transfer technology. It helps in preserving real-time rendering and maintaining strict multi-view consistency of images. This novel pipeline, which is set to be part of SIGGRAPH Asia 2024 presentations, leverages the power of Gaussian Splatting in achieving impressive and artistic style transformations over 3D scenes.
Key Features
- Real-Time Rendering: StyleGaussian allows for immediate changes and renderings, delivering the capability to see stylistic transformations instantly.
- Multi-View Consistency: Unlike traditional 3D style transfer methods that might struggle with consistency across different viewpoints, StyleGaussian ensures that the style remains coherent from any angle.
- Interactive Remote Viewer: Users can visualize and manipulate styles through an intuitive remote viewer, facilitating a convenient and engaging user experience.
Installation
For installation, StyleGaussian predominantly relies on Mamba, a speedy package manager, but it is compatible with Conda as well. Users simply need to set up the environment using a few straightforward command lines to get started.
Getting Started
The project requires pre-processed datasets and pre-trained checkpoints, which are available for download from a provided Google Drive link. Users must simply place these files in designated folders to begin experimenting with style transfer functionality.
Interactive Remote Viewer
By running the viewer script with specified model paths and style image folders, users can explore different styles easily. This tool employs Viser as a foundation for visual representation, offering the ability to tweak cameras, adjust rendering settings, and experience random styles instantly.
Inference Rendering
For those curious about direct scene transformations, StyleGaussian supports simple command executions to transfer styles to a scene using a specified style image. It also provides the feature of style interpolation, allowing for the blending of up to four style images for more complex stylistic effects.
Training
StyleGaussian supports versatile training setups:
- Training from Scratch: Users can train new models using their datasets alongside the WikiArt dataset, offering a foundational start in creative style development.
- Step-by-Step Training: The training can be broken down into three phases—reconstruction, feature embedding, and style transfer training—giving users flexibility and control over their models.
- Training with Initialization: For efficiency, users can begin training with already developed models from other scenes, saving time and resources.
Acknowledgements
The project builds on existing work, including 3D Gaussian Splatting and the StyleRF project. These foundational technologies have significantly contributed to the realization of StyleGaussian’s capabilities.
Conclusion
StyleGaussian stands out as a breakthrough in 3D style transfer technology, offering robust performance in real-time rendering and multi-view consistency. With straightforward installation and flexible training methods, alongside its innovative viewer and rendering tools, it provides both researchers and artists valuable resources to explore creative 3-dimensional styles.
