Lightness Constancy in the Presence of Specular Highlights
Color constancy is an example of subjective constancy and a feature of the human color perception system which ensures that the perceived color of objects remains relatively constant under varying illumination conditions. A green apple for instance looks green to us at midday, when the main illumination is white sunlight, and also at sunset, when the main illumination is … Webas lightness constancy. The reflectance, or albedo, of a surface is a measure of how it reflects light. For example, a typical white paper reflects 85% of its incident illumination, whereas black felt reflects only about 10%. The intensity of reflected light is called luminance (L), and it is affected by both the surface reflectance (R ... embroidery creations llc
