Anomaly Detection in Satellite Videos using Diffusion Models

Understand

The definition of anomaly detection is the identification of an unexpected event.

• Real-time detection of extreme events such as wildfires, cyclones, or floods using satellite data has become crucial for disaster management.
• Although several earth-observing satellites provide information about disasters, satellites in the geostationary orbit provide data at intervals as frequent as every minute, effectively creating a video from space.
• There are many techniques that have been proposed to identify anomalies in surveillance videos; however, the available datasets do not have dynamic behavior, so we discuss an anomaly framework that can work on very high-frequency datasets to find very fast-moving anomalies.
