We introduce ReStyle3D, a novel framework for scene-level appearance transfer from a single style image to a real-world scene represented by multiple views. This method combines explicit semantic correspondences with multi-view consistency to achieve precise and coherent stylization.

🛠️ Setup

✅ Tested Environments

• Ubuntu 22.04 LTS, Python 3.10.15, CUDA 12.2, GeForce RTX 4090/3090

• CentOS Linux 7, Python 3.12.1, CUDA 12.4, NVIDIA A100

📦 Repository

git clone [email protected]:GradientSpaces/ReStyle3D.git
cd ReStyle3D

💻 Installation

conda create -n restyle3d python=3.10
conda activate restyle3d
pip install -r requirements.txt

📦 Pretrained Checkpoints

Download the pretrained models by running:

bash scripts/download_weights.sh

🚀 Usage

We download our dataset:

bash scripts/download_data.sh

🎮 Demo (Single-view)

We include 3 demo images to run semantic appearance transfer:

python restyle_image.py

🎨 Stylizing Multi-view Scenes

To run on a single scene and style:

python restyle_scene.py   \
 --scene_path demo/scene_transfer/bedroom/  \
 --scene_type bedroom   \
 --style_path demo/design_styles/bedroom/pexels-itsterrymag-2631746

📂 Dataset: SceneTransfer

We organize the data into two components:

1. Interior Scenes: Multi-view real-world scans with aligned images, depth, and semantic segmentations.

📁 data/
  └── interiors/
      ├── bedroom/
      │   ├── 0/
      │   │   ├── images/      # multi-view RGB images
      │   │   ├── depth/       # depth maps
      │   │   └── seg_dict/    # semantic segmentation dictionaries
      │   └── 1/
      │       └── ...
      ├── living_room/
      └── kitchen/

2. Design Styles: Style examplars with precomputed semantic segmentation.
