# Qualia LeRobot Augmented Dataset

This dataset was generated by the `qualia-lerobot-augmentor` tool.

## Provenance

- Source dataset: `lerobot/aloha_static_cups_open`
- Output repo: `ian0035/aloha-static-cups-open-photometric-ui-2-tools`
- Augmentation strategy: `photometric_video_domain_randomization`
- Preset: `strong`
- Processed video files: `1`
- Processed frames: `20000`

## What changed

The LeRobot v3 format stores camera streams in `videos/` as MP4 shards, so this tool preserves the original Parquet and metadata layout and rewrites only the video files.

Each video shard receives a deterministic photometric transform sampled from the selected preset:

```json
{
"brightness": 1.059437453263347,
"contrast": 1.0809894856419886,
"saturation": 1.1324629705856533,
"hue_shift": -12,
"gamma": 0.9133748445065928,
"noise_std": 0.007226479063663269
}
```

That makes the dataset more robust to changes in lighting, color response, and sensor noise while keeping episode timing and shard boundaries stable.
