    Reconnaissance Suite

ISR Suite

Uurmi have custom solution for bio-inspired saliency, attention, and search algorithms, neural·algorithms for object recognition, activity recognition, context extraction, multi-sensor fusion, and rea soning engine for exploitation. Our solutions use state of the art proven algorithms which can be easily ported on to target hardware for real-time operation in tactical, operational, and forensic applications.


Persistent Surveillance
