Target acquisition: Human observer performance studies and TARGAC model validation (Final Report)

Human target acquisition performance was studied using the thermal imagery that was collected during Battlefield Emissives Sources Trials under the European Theater Weather and Obscurants, (BEST TWO), organized by NATO AC243/Panel4/RSG.l5 in 1990. Recognition and identification probabilities were measured for a large number of stationary and...

Image enhancement and moving target detection in IR image sequences

Results are presented of noise reduction by motion compensated temporal filtering in a noisy IR image sequence and of moving target detection in an air-to-ground IR image sequence. In the case of motion compensated temporal filtering our approach consists of estimating the optical flow between successive frames and subsequently averaging a small...

Onbemande grondsensors

De grote beweeglijkheid en vuurkracht van moderne strijdkrachten en daardoor de snel wisselende gevechtssituaties zullen in een toekomstig conflict snelle beslissingen vereisen. Voorwaarde voor een snelle besluitvorming is dat commandant en staf voortdurend op de hoogte zijn van de situatie, zowel van eigen als van vijandelijke troepen.
