The goal of color constancy is to measure image colors despite
differences in the color of the light source. Traditionally, the
computational method of obtaining this ability is by using pixel
values only. Recently, methods using edges instead of pixel values
have been proposed. However, different edge types exist, such
as material, shadow and specular edges. Therefore, in this paper,
the main goal is to analyze the influence of different edge types
on the performance of edge-based color constancy. It is shown
that, on generated data without color clipping, specular edges
deliver near-perfect color constancy and that shadow edges are
more valuable than material edges. However, with color clipping,
the performance using the specular edges decreases significantly,
while the performance using the material or shadow
edges is less affected.
