Abstract
Estimates of the incidence of metameric surfaces, defined as having different spectral reflectances but appearing the same under a given light, were obtained from 40 hyperspectral images of natural scenes. The degree of metamerism was specified with respect to a color-difference metric after allowing for full chromatic adaptation to the scene. Although the proportion of pairs of surfaces in an image that were metameric was very low, between about 10 -44 and 10 -5, the relative proportion, i.e. of pairs indistinguishable under one of the daylights that were metameric was high, of the order of 10 -1, depending on the type of scene and criterion degree of metamerism. The proportion of metamers in scenes containing foliage was generally higher than in scenes containing man-made structures, and this difference increased as the degree of metamerism increased.
