Summation Of Perceptual Cues In Natural Visual Scenes

Observers viewed pairs of slightly different photographs of natural scenes, rating the perceptual difference between them. If an image pair differs in two ways, how big is the perceptual difference compared to when images differ in only one way? It is well established that detection thresholds for combinations of sinusoidal gratings are empirically governed by "Quick pooling" or "Minkowski summation".
