Brightness Illusions as Optimal Percepts - Technical Report: NUIM-CS-TR-2006-02
Jaramillo, Santiago ; Pearlmutter, Barak A.
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.
