Colorimetric characterization of scanner by measures of perceptual color error

Colorimetric Scanner Calibration for Textiles by Neural-Network

In this study, colorimetric calibration of scanner has been done via perceptron neural network with three or four layers by back propagation algorithm for colored polyester fabrics. The results obtained for random training samples are not satisfactory but application of selective training samples for L*a*b* or RGB leads to good results, with better results obtained for the L*a*b* method. On the...

Measures of Goodness for Color Scanners

Color errors in scanners arise from two sources: the non-colorimetric nature of the scanner sensitivities and the measurement noise. Several measures of goodness have been used to evaluate scanners based on these errors. In this paper, the trustworthiness of these measures is studied through simulations. A new measure incorporating both the above sources of errors and providing excellent agreem...

Colorimetric and spectral characterization of a color scanner using local statistics

The Effects of Illuminants and Standard Observers ‎Combination on Relationship between Spectrophotometric ‎Error and Colorimetric Inaccuracy

The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a ‎new method is introduced for determining the relationship between spectrophotometric ‎error and colorimetric inaccuracy. The error propagation in colorimetric parameter ‎calculation is evaluated using a linear relation between variance of reflectance spectra ‎and CIE tristimulus values. This linear formula ca...
