Color Based Object Recognition

Assuming white illumination and dichromatic reflectance, we propose new color models c1c2c3 and l1l2l3 invariant to the viewing direction, object geometry and shading. Further, it is shown that l1l2l3 is also invariant to highlights. Further, a change in spectral power distribution of the illumination is considered to propose a new photometric color invariant m1m2m3 for matte objects.
