# SynthBench

Benchmark dataset for evaluating synthetic data generation methods for visual classification. Contains real iPhone photos, FLUX text-to-image generated images, and programmatically augmented synthetic images across 6 object classes.

## Classes

mouse, pen, phone, laptop, water bottle, Rubik's cube

```

## Usage

```python
from huggingface_hub import snapshot_download

# Download everything
snapshot_download(repo_id="LakshC/SynthBench", repo_type="dataset")

# Download only real images
snapshot_download(repo_id="LakshC/SynthBench", repo_type="dataset", allow_patterns="data/real/*")
```

Or via CLI:

```bash
huggingface-cli download LakshC/SynthBench --repo-type dataset
```

## Model

All checkpoints are ResNet-18 (via `timm`), fine-tuned for 6-class classification.
