Forest Fire Detection Dataset — Auto-Annotated

Bounding-box annotated version of touati-kamel/forest-fire-dataset, built for training forest-fire / smoke / fog object detection models.

Overview

This dataset contains video frames auto-labeled with bounding boxes for fire and smoke-related visual phenomena, using a zero-shot open-vocabulary object detector (Grounding DINO). It is derived from the original touati-kamel/forest-fire-dataset image classification dataset, which did not include bounding box annotations.

Classes

Class Description
Fire Visible flame
Fire-smoke Smoke originating from fire
Fog Fog / mist in the scene
Factory-smoke Industrial/factory smoke (non-fire smoke source)

Why a single train split?

The source frames were extracted from videos and then shuffled randomly before being split into train/validation/test. Because consecutive video frames are often 99%+ visually similar, this shuffling caused near-duplicate frames from the same video clip to end up scattered across different splits -- a data leakage problem that would make validation/test metrics unreliable (a model could "memorize" a near-identical frame seen during training).

To fix this, all annotated frames from the original train/validation/test splits have been merged into a single train split here. Validation and test splits will be added later, sourced from separate, distinct videos not present in train, to ensure clean evaluation without leakage.

Annotation methodology

  • Model: IDEA-Research/grounding-dino-tiny (zero-shot, open-vocabulary object detection), run via Hugging Face transformers.
  • Prompts used (mapped to class names):
    • "flame"Fire
    • "smoke from fire"Fire-smoke
    • "fog"Fog
    • "industrial smoke"Factory-smoke
  • Thresholds: box confidence >= 0.30, text matching threshold >= 0.25.
  • Important: these are automatically generated (teacher-model) annotations, not human-verified. Expect some false positives/negatives, especially on visually ambiguous frames (heavy haze, distant smoke, low light). Manual review or a secondary verification pass is recommended before using this data for anything beyond bootstrapping a first model.

Schema

Column Type Description
image Image Original, unannotated frame
detections list[dict] One entry per detected box: {"class": str, "bbox_xyxy": [x1,y1,x2,y2], "confidence": float}
yolo_labels string Same boxes pre-converted to YOLO format (class_id x_center y_center width height, normalized 0-1), one line per box, ready to write directly to .txt label files
image_annotated Image (optional, some chunks) Visual copy of image with boxes/labels drawn, for quick QA

Class-to-ID mapping for yolo_labels is stored in classes.json at the repo root: {"0": "Fire", "1": "Fire-smoke", "2": "Fog", "3": "Factory-smoke"} (order-dependent list).

Usage

from datasets import load_dataset

ds = load_dataset("touati-kamel/forest-fire-annotations")
example = ds["train"][0]
print(example["detections"])
print(example["yolo_labels"])

Converting to a YOLO training folder

import os

os.makedirs("yolo_dataset/images/train", exist_ok=True)
os.makedirs("yolo_dataset/labels/train", exist_ok=True)

for i, example in enumerate(ds["train"]):
    example["image"].save(f"yolo_dataset/images/train/{i:07d}.jpg")
    with open(f"yolo_dataset/labels/train/{i:07d}.txt", "w") as f:
        f.write(example["yolo_labels"])

Roadmap

  • Add genuinely separate validation and test splits from new, distinct video sources (not derived from frames already in train).
  • Optional human-in-the-loop verification pass on a sample of auto-labeled boxes to estimate label quality/precision.
