Datasets:
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.
