On Lightness Computation in Mondrian World

Abstract

The retinex theory of lightness computation explains how for a “Mondrian World” image, consisting of a number of patches each of uniform reflectance, the reflectances can be computed from an image of that object. The computation can be realised as a parallel process performed by successive layers of cooperating computational cells, arranged on hexagonal grids. The layers will, in practice, be of finite extent and it is critical that cells on the array boundary behave correctly. The process has been successfully implemented on a digital computer.
