Weighted LabPQR Interim Connection Space Based on Human Color Vision for Spectral Color Reproduction

Spectral Color Processing Using an Interim Connection Space

The use of an Interim Connection Space (ICS) is proposed as a means for extending the concept of device independent color management to support spectral imaging. Color management, in its standard practice, relates color rendering capability of devices through a Profile Connection Space (PCS). The International Color Consortium (ICC) defines a set of encodings for PCS derivable from CIEXYZ. Mult...

Representing Spectral data using LabPQR color space in comparison to PCA method

In many applications of color technology such as spectral color reproduction it is of interest to represent the spectral data with lower dimensions than spectral space’s dimensions. It is more than half of a century that Principal Component Analysis PCA method has been applied to find the number of independent basis vectors of spectral dataset and representing spectral reflectance with lower di...

Spectral Color Reproduction Based on Six-Color Inkjet Output System

Spectral Gamut Mapping Framework based on Human Color Vision

A new spectral gamut mapping framework is presented. It adjusts the reproduction, choosing spectra within the printer's gamut that satisfy colorimetric criteria across a hierarchical set of illuminants. For the most important illuminant a traditional gamut mapping is performed and for each additional considered illuminant colors are mapped into device and pixel dependent metamer mismatch gamuts...

Spectral Color Reproduction of Paintings

A spectral-based imaging system was constructed consisting of a two-sequential-absorption-filter-CFA digital camera and a seven-color inkjet printer and used to image and print a post-impressionist style painting such that matches were generated for CIE Illuminants D65 and A. Camera calibration was learning based using the Matrix R method. Rendered images for both illuminants were inputted to a...
