NIH Chest X-ray14 - 320x320 Processed for CheXVision

This dataset repackages the raw NIH Chest X-ray14 source dataset from alkzar90/NIH-Chest-X-ray-dataset into a data-only Parquet dataset for the CheXVision project.

Dataset Summary

• Source format: 12 ZIP archives of original chest X-ray images plus CSV manifests
• Output format: data-only Parquet shards under data/
• Resolution: 320x320 RGB
• Columns: image, labels, filename
• Split contract: train, validation, test
• Approximate local Parquet size produced in this run: 7.4 GB

Splits

Split	Images
Train	77,967
Validation	8,557
Test	25,596

Schema

• image: 320x320 RGB image payload
• labels: pipe-delimited pathology labels, or No Finding
• filename: original NIH image filename

Processing Notes

• Source split manifests come from train_val_list.txt and test_list.txt
• Validation membership uses the same stable hash-bucket logic as the live HlexNC/chest-xray-14 dataset
• Hidden __MACOSX ZIP entries and non-image members are ignored
• Truncated-but-readable images are kept; truly unreadable files are skipped
• This repo intentionally ships no load_dataset.py script so it remains a data-only dataset that works with the modern HF dataset viewer

Usage

from datasets import load_dataset

dataset = load_dataset("HlexNC/chest-xray-14-320")
print(dataset)

Provenance

Built by the Kaggle kernel hlexnc/chexvision-resize-320 for the CheXVision project.
