# 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.
