# CoherentGS-DL3DV-Blur Dataset
|
| 14 |
|
| 15 |
+
CoherentGS tackles one of the hardest regimes for 3D Gaussian Splatting (3DGS): Sparse inputs with severe motion blur. We break the "vicious cycle" between missing viewpoints and degraded photometry by coupling a physics-aware deblurring prior with diffusion-driven geometry completion, enabling coherent, high-frequency reconstructions from as few as 3β9 views on both synthetic and real scenes.

## Sample Usage
|
| 72 |
+
### Installation
|
| 73 |
+
Tested with Python 3.10 and PyTorch 2.1.2 (CUDA 11.8). Adjust CUDA wheels as needed for your platform.
|
| 74 |
+
|
| 75 |
+
```bash
|
| 76 |
+
# (Optional) fresh conda env
|
| 77 |
+
conda create --name CoherentGS -y "python<3.11"
|
| 78 |
+
conda activate CoherentGS
|
| 79 |
+
|
| 80 |
+
# Install dependencies
|
| 81 |
+
pip install --upgrade pip setuptools
|
| 82 |
+
pip install "torch==2.1.2+cu118" "torchvision==0.16.2+cu118" --extra-index-url https://download.pytorch.org/whl/cu118
|
| 83 |
+
pip install -r requirements.txt
|
| 84 |
+
```
|
| 85 |
+
|
| 86 |
+
### Data
|
| 87 |
+
Download DL3DV-Blur and related assets from this Hugging Face dataset.
|
| 88 |
+
Place downloaded data under `datasets/` (or adjust paths in the provided scripts).
|
| 89 |
+
|
| 90 |
+
### Training
|
| 91 |
+
Train on DL3DV-Blur (full resolution) with:
|
| 92 |
+
```bash
|
| 93 |
+
bash run_dl3dv.sh
|
| 94 |
+
```
|
| 95 |
+
For custom settings, start from `run.sh` and tweak dataset paths, resolution, and batch sizes.
