The author shows that Mach bands and other high-pass filter effects can be created by purely positive pointspread functions without inhibition. In addition if one attempts to combine lateral inhibition with constant volume operation, the results are dramatically wrong: the edge response always contains Mach bands that bulge in the wrong direction. Thus within the nonlinear theoretical framework provided by constant volume operators, lateral inhibition is neither necessary nor sufficient for modeling Mach bands and other high-pass filter properties of spatial vision.
