Color gamuts of acrylic paints generated by paint mixing and varnishing is introduced. A colorant data including unit k, unit s, and Saunderson coefficients, K1 and K2, are optimized. The simulation result of paint gamut rendering contradicts a belief of color mixing theory that yellow, blue, and red primaries produces any green. In addition, a statistic gloss model shows that varnishing makes ...

Hair shine or luster is perceived as an important, though analytically somewhat elusive, attribute of beauty, primarily associated with clean and healthy hair. Principles for the assessment of hair luster are developed that are consistent with the practical situation. These principles are related to the components of light, specularly and diffusely reflected from single hair fibers, as measured...

Images have characteristic statistics that can be characterized in terms of the responses of wavelet or Gabor-like filters. There has been a great deal of interest in the fact that images have sparse (kurtotic) statistics in the wavelet domain, with implications for efficient image encoding in biological and artificial systems. If we set aside the issue of efficiency, we are still left with the...

This paper investigates the visual appearance of printed special effect colors that become increasingly popular in high-quality printing. Since traditional colorimetry is insufficient to assess the unique visual appearance of such prints, improved perceptionbased measures and tolerances are necessary for process control and quality assurance. A prerequisite for developing such measures is a tra...

The image of a material's surface varies not only with viewing and illumination conditions, but also with the material's surface properties, including its 3-D texture and specularity. Previous studies on the visual perception of surface material have typically focused on single material properties, ignoring possible interactions. In this study, we used a conjoint-measurement design to determine...

Language users are increasingly turning to electronic resources to address their lexical information needs, due to their convenience and their ability to simultaneously capture different facets of lexical knowledge in a single interface. In this paper, we discuss techniques to respond to a user’s lexical queries by providing multilingual and multimodal information, and facilitating navigating a...
