SEERS (Snapshot Spectral Imager for IR Surveillance) will develop a modular, compact and cost effective snapshot spectral imaging system in the infrared domain (0.7-14 µm wavelength). It will be endowed with embedded vision and cognitive fusion capabilities. Robust visibility, robust temperature imaging, gas detection and discrimination, and spill detection will enable event-driven video analysis. Breakthrough performance will be demonstrated in two relevant application scenarios: coastal and road tunnel surveillance.
