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...

background: cervical cancer has been shown to be highly associated with human papillomavirus (hpv) infection. the viral oncogenes e6 and e7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. in the present study, it was investigated the potential effect of hpv-16 e6, e7 and l1 co-administration to activate specific cytotoxic t lymph...

abstract background ulcerative colitis (uc) is characterized by recurrent episodes of inflammation limited to the mucosal layer of the colon. calprotectin is a zinc and calcium binding protein derived from neutrophils and monocytes. it is easily detectable in tissue samples, body fluids, and stools, which makes it a potentially valuable marker of inflammation. the aim of the current study is to...
