WebNov 27, 2012 · First, weights decline with distance from the target surface whose lightness is being computed. Second, larger weights are given to edges whose dark sides point towards the target. Third, edge integration is carried out along a path leading from a common background field, or surround, to the target location. WebOne lowpass filter is used for constructing a background brightness. This model explains Mach bands by the fact that simple cells cannot discriminate between ramp edges and lines, such that positive and negative lines are produced at ramp edges.

WebWhen a patch is surrounded by two or more regions with different luminances, a plausible extension of the ratio rule would predict that the effect of the surrounding regions should correlate with the length of the border they share with the test patch. WebUnder these circumstances, assimilation occurs: appears darker than , even though the immediate contexts of both and are identical in the bullseye and simultaneous contrast …
