....that could have resulted in exactly the same set of sensor responses. In terms of color reproduction this would create no problem, if as seen in the earlier example, camera sensors were fooled by the same metamers as the human eye i.e. if camera metamers were the same as eye metamers (cf. [16]) As Horn has pointed out [12] eye metamers and camera metamers can only be made to coincide when the sensor curves of the two systems are a homogeneous linear transformation away from each other. Unfortunately, this linear relationship between response curves for machine and human vision does ....
....analogous manner, but with the 1931 CIE standard observer color matching functions instead of the sensor response curves R k . These 2 Note that to determine the correct R k it is necessary to calibrate the camera system carefully for contributions from the lens system, the digitizer, etc. cf. [16]) Natural Metamers 7 curves are commonly called x; y; z, but for convenience we shall denote the collection of three curves by x k and the collection X,Y,Z by X k : X k = Z C( x k ( d : 2) Our task is to generate from the ae k those values X k that best match the X k that would have ....

....PSM images can be combined with photometric and colorimetric attributes. Since PSM additionally recovers surface albedo values, illumination independent surface color descriptors can be obtained. From these color descriptors a set of CIE tristimulus values can be assigned to each surface element [14 16] without using a spectroradiometer. Moreover, from the separated specular reflection component and the surface normals it is possible to extract roughness values of uniform colored surface regions that possess a non zero specular reflection component [17] 4 Results We have tested the separation ....
