Reflectance function estimation from tristimulus values
Information about the spectral reflectance of a color surface is useful in many applications. Assuming that reflectance functions can be adequately approximated by a linear combination of a small number of basis functions and exploiting genetic algorithms, we address here the problem of synthesizing a spectral reflectance function, given the standard CIE 1931 tristimulus values. Different sets ...
متن کاملEstimating Surface Reflectance Functions from Tristimulus Values
Information about the spectral reflectance of a color surface is useful in many applications. Assuming that reflectance functions can be adequately approximated by a linear combination of a small number of basis functions, we address here the recovery of a surface reflectance function, given the tristimulus values under one or more illuminants.
متن کاملSpectral Color Reproduction from CIE Tristimulus Values Using a Node Address Array Selection Technique
This study proposes a feasible method for spectral color reproduction based on a node address array selection technique from CIE tristimulus values. In this method three-dimensional lookup table (3-D LUT) has been constructed to connect the node address array and the spectrum as the source and destination spaces. First we present a general framework for how to reproduce spectral color. Then res...
متن کاملTowards A Unified Method For Computing Tristimulus Values
Tristimulus values (TSV) form the basis of colorimetry. They are transformed to other colorimetric coordinates for industrial applications such as colour specification, colour quality control, colour difference evaluations, device characterization for cross-media colour reproduction and recipe formulation. Accurate calculation of TSVs is highly desired by industry for open environment communica...
متن کاملSpectral Response Based Calibration Method of Tristimulus Colorimeters
A new method is described to calibrate tristimulus colorimeters for high accuracy color measurements. Instead of traditional lamp standards, modern, high accuracy detector standards are suggested for calibration. After high accuracy absolute spectral response determination of the tristimulus receivers, color (spectral) correction and peak (amplitude) normalization can minimize uncertainties cau...
