This study was undertaken in an effort to relate ANVIS-6 Night Vision Goggle
image quality to user performance. The purpose was to determine which of five image
quality metrics best related to performance tasks. The image quality metrics examined
Modulation Transfer Function Area (MTFA), Integrated Contrast Sensitivity (leS),
Square Root Integral (SQRI), Resolution, and Signal-to-Noise Ratio (SNR). The
performance tasks were detection and recognition of targets under various levels of
moon illumination. The metric that best related to target detection was SNR. The
SNR results are consistent with visual psychophysics and SNR effects. The metric that
best related to target recognition was Resolution. The resolution results are consistent
with the position that recognition performance improves for suprathreshold targets as
resolving power increases.
