Improved image quality metric for predicting tactical vehicle identification

摘要

Three perception experiemtns were conducted to quantify the relationship between tactical military vehicle identification (ID) performance hwen using an imager and the Modulation Transfer Function (MTF) and noise characteristics of that imager. The results of these experiemnts show that the limitng resolutionmetric provides a reasonably accurate prediction of target ID performance. For example, limiting resolution is a better predictor of perfomrance than Modulation Transfer Function Area or integrated contrast Sensitivity. Howeve,r a metric consisting of itnegrating the square root of the product of Contrast Sensitivity and spatial frequency provides a better fit to data than limiting resolution.
