Abstract:
As hypothesized by Gaspard Monge in the eighteenth century, white surfaces have a unique
property that
distinguishes them from other coloured specular surfaces. We test his hypothesis using
modern digital
imagery and find it to hold. We then incorporate it into an algorithm that identifies white
surfaces when
the illumination colour is unknown. Since white surfaces reflect the colour of the incident
illumination,
the method also has application to the problem of illumination estimation for colour constancy.
