....have a great impact on the change in color appearance. Most color based systems are sensitive to these changes. There are two major approaches for handling environmental changes. The first approach finds the effects that change the color and use them as inverse filter to obtain the real color [11] [12] 13] The second approach, adaptive color segmentation, adapts the previously developed color model to the changing environ ment [ 1] 3] This approach is more suitable to compensate for changes in the natural environment. However, just adapting color may not achieve the robustness ....

....incandescent lighting (illuminant A) a variety of standard daylights at correlated colour temperatures from 4800 # to 10000 # , and a standard fluorescent. Thus, with the reflectances, the set C has 5056 members. Under each of the illuminants the set of measured RGB s forms a convex set [13]. Since we are not here concerned with brightness, we can form a 2D convex set for each illuminant by forming the chromaticities r = R=#R G B#, g = G=#R G B# and form the convex hull of the convex hulls of #r;g# values (cf. 14] These chromaticities can then be turned back into RGB ....

....Dupont dye reflectances, and Macbeth ColorChecker reflectances. To form colour signals from these reflectances, let us use 11 illuminant spectra: A, D50, D65, D75, two fluorescent illuminants, and several measured SPDs. Under each of the illuminants the set of calculated RGB s forms a convex set [9]. Let us impose the reasonable constraint that the non negativity of RGB points corresponding to the overall convex hull of the set R be maintained under a transform (19) Suppose the boundary set of RGB values is f R , with f R an e n s matrix, where e n is the number of samples ....
