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 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 کاملUsing adaptive matrix Correction Method for decreasing colour measuring systematic error in tristimulus colorimeters
In image taking colorimetry the tristimulus technique is still the practical viable method if the measuring time should be kept in limits. Due to the fact that the number of coloured glasses that are available to adjust the detector responsivity to the CIE colour matching functions (CMF) is limited and the number of the filters used in a channel can not be increased without limits to decrease t...
متن کاملCorrelation Between Scanner Response and CIE Tristimulus Values
In this study, a relationship between scanner response (RGB) and CIE tristimulus values (XYZ) is established by regression technique with different polynomials for colored polyester fabrics. The results showed that the transformation process is material dependent and higher order polynomials will fit the experimental data better than lower polynomials. The results also showed that the way the c...
