Abstract

Color constancy refers to the phenomenon that our perception of a color stays constant even if the illuminating light changes composition. The current study is an attempt to make a machine vision model that correctly identifies the color of a section of a Mondrian display (a poster made of many colored sheets of paper named after the painter Piet Mondrian) regardless of the spectral composition of the illumination. We start with a discussion of previous color constancy research, with a large focus on the studies by E.H. Land (1977 & 1986). Then we discuss how well our program functions at identifying the color of a portion of the Mondrian display in photographs taken under various lighting conditions.
