Brightness Illusions as Optimal Percepts - Technical Report: NUIM-CS-TR-2006-02.
National University of Ireland Maynooth.
We show that Mach bands and a number of other low-level brightness illusions
can be accounted for by assuming that the perceptual system performs simple
Bayesian inference using a Gaussian image prior with noisy retinal gangion cells.
This theory accounts for phenomena which have proven problematic for simple
energy-based and lateral-interaction models while avoiding the complexities of
mid-level vision theories that involve the estimation of structure and albedo.
