Abstract
Observers viewed a simulated airport runway landing scene with an obstructing aircraft on the runway and rated the visibility of the obstructing object in varying levels of white fixed-pattern noise. The effect of the noise was compared with the predictions of single and multiple channel discrimination models. Without a contrast masking correction, both models predict almost no effect of the fixed-pattern noise. A global contrast masking correction improves both models' predictions, but the predictions are best when the masking correction is based only on the noise contrast (does not include the background image contrast).
