Abstract
The forward looking infrared subsystem of the Northrop Grumman LITENING II targeting pod incorporates a plateau algorithm for automated gain control (AGC) to enhance the image display for visual detection and identification of targets. We developed an adaptive, automated algorithm to optimize the input parameters of the baseline plateau AGC in real time based on rudimentary features of the intensity histogram. The optimized plateau algorithm retains the desired contrast enhancement provided by the baseline algorithm while maintaining an overall balance of target and background intensities without unacceptable boosts in noise levels.
