Comprehensive Flame Dataset - Validation Split

This repository provides the existing validation split of the Comprehensive Flame Dataset (fire_rgb), the visible-light flame dataset associated with the Small-Scale Fire Datasets project and the paper FireDet: A framework for precise detection and localization of small-scale fire.

Only the original validation split is provided here. No training split is included, and no new split has been generated. The counts below describe this release, rather than the totals for other datasets described by the paper or project.

Content	Count
Validation images	2,424
JPEG images	2,133
PNG images	291
YOLO TXT label files	2,424
Original XML annotation files	2,424
Fire bounding boxes in YOLO labels	3,231
Fire bounding boxes in XML annotations	3,231
Additional smoke bounding boxes in XML annotations	576
Empty YOLO label files	899

images/val/         # Original validation images
labels/val/         # Original YOLO labels; class 0 = fire
annotations/val/    # Original XML annotations; fire and smoke
manifest.json      # Relative paths, byte sizes and SHA-256 of all 7,272 data files
SHA256SUMS         # SHA-256 checksums of the same data files
README.md

Images and annotation files are preserved byte for byte, including their original filenames. Operating-system thumbnails and training caches are excluded. The raw images and annotations together occupy approximately 2.14 GB (decimal).

Annotation formats

Each image is paired with one TXT and one XML file with the same filename stem.

YOLO TXT: each nonempty line is 0 x_center y_center width height, with coordinates normalized to image dimensions. The single class is 0: fire. Empty TXT files are intentional: these images have no fire boxes in the supplied labels and are retained for validation. An empty fire label does not imply that an image has no smoke.

Original XML: the original annotations also include smoke. XML and TXT therefore have different class coverage; the XML fire object count matches the corresponding TXT count for every image. XML files retain their original <path> values; those values refer to the source annotation environment and should not be used as download paths. Resolve images using images/val/<filename> instead.

For fire-only evaluation with the associated project, use labels/val. XML is supplied as the original additional annotation resource; do not assume that TXT includes smoke labels.

Download

Install the Hugging Face client and download the dataset:

pip install --upgrade huggingface_hub
hf download yang1002/comprehensive-flame-dataset-validation --repo-type dataset --local-dir comprehensive-flame-dataset-validation

Or use Python:

from huggingface_hub import snapshot_download

snapshot_download(
    repo_id="yang1002/comprehensive-flame-dataset-validation",
    repo_type="dataset",
    local_dir="comprehensive-flame-dataset-validation",
)

For reproducible use, pass a specific commit SHA as --revision to the CLI or revision= to snapshot_download. All data files can be checked against manifest.json or SHA256SUMS.

License and provenance

No dataset license has been specified for this release. Public availability does not itself grant a particular reuse license. Do not infer a data license from the project code, its dependencies, or the paper. Consult the dataset owner regarding reuse and any underlying source-specific terms.

The associated project describes data collected in experiments together with public fire-related data. This release preserves the existing validation files; it does not provide a verified per-image provenance map. See the project and paper for the experimental context.
