3 - D Hardcopy : The Hosoya Cube

Much effort in scientific visualization is put towards the representation and communication of three-dimensional objects. Typically, an investigator labors in front of a graphics workstation, twiddling knobs and flipping switches until meaningful views of the object are created. Once the investigator has found the correct representation of the data, the problem arises of how to communicate this...

Tetra-chroma Display: Color Accuracy between Soft-proofing and Hardcopy

This paper introduces tetra-chroma display unit that has, in contrast to the contemporary trichromatic displays, four primary colors. Extra fourth cyan light allows better reproduction not only region of cyan colors but also, thanks to advanced position of green primary light, orange and yellow colors. These both regions are printable through modern inkjet printers. Colorimetric driving is disc...

Spectral reproduction from scene to hardcopy: II. Image processing

Traditional image processing techniques used for 3and 4band images are not suited to the many-band character of spectral images. A sparse multi-dimensional lookup table with inter-node interpolation is a typical image processing technique used for applying either a known model or an empirically derived mapping to an image. Such an approach for spectral images becomes problematic because input d...
