Thermal anomaly detection
Identifies localised high-temperature events against background radiance; good for active fire detection, gas flare monitoring, and volcanic hotspot mapping.
Contextual or fixed threshold applied to mid-wave or longwave IR channels. High saturation risk over intense sources requires careful gain settings. MWIR (~3.5-4 um) is more sensitive to sub-pixel hot targets than LWIR. Wikipedia: Wildfire
