Forest-Fire-Detection is a vision-language encoder model fine-tuned from google/siglip2-base-patch16-512 for multi-class image classification. It is trained to detect whether an image contains fire, smoke, or a normal (non-fire) scene. The model uses the SiglipForImageClassification architecture.

Intended Use

Forest-Fire-Detection is designed for:

Wildfire Monitoring – Rapid identification of forest fire and smoke zones.
Environmental Protection – Surveillance of forest areas for early fire warning.
Disaster Management – Support in emergency response and evacuation decisions.
Smart Surveillance – Integrate with drones or camera feeds for automated fire detection.
Research and Analysis – Analyze visual datasets for fire-prone region identification.
