Dynamic decorrelation as a unifying principle for explaining a broad range of brightness phenomena
Fig 16
Model predictions for Dungeon, Checkerboard and Shevell.
In each display, the gray areas have the same luminance, yet they are perceived differently because of assimilation with the adjacent structures. (A) Top: Dungeon illusion. Middle, corresponding gain control map. Bottom, profile plot of the estimated brightness (red line) compared with the input (black line). (B) Checkerboard illusion. (C) Shevell’s Rings. Notice that this illusion cannot be explained with T-junctions.
