| # Split assignments and excluded subjects |
|
|
| One folder per real X-ray source used in the FleXray paper, including the sources |
| we cannot redistribute, so the exact partitions and quality-control exclusions can |
| be rebuilt from the original downloads. Paths are relative to each source's |
| download directory and contain no image data. |
|
|
| ## `<Dataset>/splits.csv` |
|
|
| Every image that FleXray trained or evaluated on. |
|
|
| | column | meaning | |
| |---|---| |
| | `sample_id` | FleXray sample key (matches `dataset.yml` for redistributed sources) | |
| | `subject_id` | patient/subject grouping key; all samples of a subject share one split | |
| | `split` | `train`, `val`, or `test` as used in the paper | |
| | `source_path` | image path relative to the original download (`''` when the source has no per-image file) | |
|
|
| All results in the paper are scored on `test`; `val` was used only for model development. |
|
|
| ## `<Dataset>/exclusions.csv` |
|
|
| Every image removed before split assignment. An empty file means nothing was excluded. |
|
|
| | column | meaning | |
| |---|---| |
| | `subject_id` | FleXray subject key of the excluded image (`''` for source files that were never annotated) | |
| | `source_path` | image path relative to the original download when known | |
| | `reason` | one of the reasons below | |
| | `detail` | human-readable note, source filename, or scope | |
|
|
| | `reason` | applied when | |
| |---|---| |
| | `manual_review` | the annotation was flagged as unreliable during manual review (`detail` gives the reason where documented) | |
| | `duplicate_image` | the pixels exactly duplicate another image; one representative is kept | |
| | `empty_mask` | the annotation has no foreground after mapping into the FleXray label protocol | |
| | `missing_local_image` | the annotation references an image absent from the downloadable image set | |
| | `landmark_out_of_bounds` | AASCE: landmark coordinates fall outside the image | |
| | `corrupt_zero_filled_png`, `out_of_bounds_femur_polygon` | MTDDH: source image or polygon is unusable | |
| | `not_referenced_by_dataset2_coco` | MTDDH: PNG present in the archive but absent from the Dataset2 annotations | |
|
|
| All criteria were fixed before any model was scored and apply identically to FleXray |
| and every baseline. These files are generated by |
| `scripts/release/export_split_manifests.py` in the OmniAX repository. |
