| Popis: | This is the copy of journal's version originally published in Proc. SPIE 6807. Reprinted with permission of SPIE: http://spie.org/x10.xml?WT.svl=tn7 We have defined an inverse model for colorimetric characterization of additive displays. It is based on an optimized three-dimensional tetrahedral structure. In order to minimize the number of measurements, the structure is defined using a forward characterization model. Defining a regular grid in the device-dependent destination color space leads to heterogeneous interpolation errors in the device-independent source color space. The parameters of the function used to define the grid are optimized using a globalized Nelder-Mead simplex downhill algorithm. Several cost functions are tested on several devices. We have performed experiments with a forward model which assumes variation in chromaticities (PLVC), based on one-dimensional interpolations for each primary ramp along X, Y and Z (3×3×1¿D). Results on 4 devices (2 LCD and a DLP projection devices, one LCD monitor) are shown and discussed. |
