Flood-Image-Detection

Flood-Image-Detection is a vision-language encoder model fine-tuned from google/siglip2-base-patch16-512 for binary image classification. It is trained to detect whether an image contains a flooded scene or non-flooded environment. The model uses the SiglipForImageClassification architecture.

Intended Use

Flood-Image-Detection is designed for:

• Disaster Monitoring – Rapid detection of flood-affected areas from imagery.
• Environmental Analysis – Track flooding patterns across regions using image datasets.
• Crisis Response – Assist emergency services in identifying critical zones.
• Surveillance and Safety – Monitor infrastructure or locations for flood exposure.
• Smart Alert Systems – Integrate with IoT or camera feeds for automated flood alerts.
