LayeredFlow-Syn
This release contains 15,549 synthetic samples across scenes 0–29. Every sample has a ground-truth Parquet and a matching RGB Parquet. Together, the 31,098 Parquet files contain ground-truth annotations and 62,196 original PNG images.
For sample 20_0, the pair is:
| File | Contents |
|---|---|
| data/20/20_0.parquet | Ground truth, including flow, masks, positions, and sample metadata |
| data/20/20_0_rgb.parquet | frame0_l.png, frame0_r.png, frame1_l.png, frame1_r.png, and info.json, in that order |
The four PNGs give left and right camera views for two consecutive frames. Use sample_id to pair the images with the annotations. Each Parquet row represents a file within a sample. The relative_path column identifies that file, content contains its original bytes, and sha256 and num_bytes let you check the contents.
All 25,261 Parquets from the Princeton release are included. This release also restores the 5,837 matching RGB Parquets for scenes 19–29 using the LayeredFlow-Syn archive on Della. Restored files follow the original RGB Parquet schema and preserve the PNG bytes.
For the original ground-truth layout, attribution, and license metadata, see the original dataset card.
