Dynamic decorrelation as a unifying principle for explaining a broad range of brightness phenomena

Model predictions for Hermann/Hering grid and corrugated grid.
(A) Hermann/Hering (HG) illusion and a corrugated version of it. At the intersections of the white grid lines, illusory gray spots are perceived in the HG, but not in the corrugated grid. (B) The corresponding gain control maps of the input images of A. (C) The brightness estimation from our model. The surfaces plots (insets) illustrate the 3D profile of the brightness estimation corresponding to regions highlighted with red. (D) The predicted brightness magnitude at the intersections as a function of the ratio , where the red curve corresponds to the corrugated grid, and the blue curve to the HG.
