Paper Abstract

The probability of detection (Pd) of targets in static infrared and visually cluttered scenes is computed using the fuzzy logic approach (FLA). The FLA is presented as a robust method for the computation and prediction of the Pd of targets in cluttered scenes. The Mamdani/Assilian and Sugeno neuro-fuzzy-based models are investigated. A large set of infrared (IR) imagery and a limited set of visual imagery are used to model the relationships between several input parameters: the contrast, camouflage condition, range, aspect, width, and experimental Pd. The fuzzy and neuro-fuzzy models gave predicted Pd values that had 0.98 correlation to the experimental Pd’s. The results obtained indicate the robustness of the fuzzy-based modeling techniques and the applicability of the FLA to those types of problems having to do with the modeling of human-in-the-loop target detection in any spectral regime.
