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...

statement of problem: targis restorations provide good esthetic and clinical success; however, improving marginal accuracy requires further investigations. purpose: the aim of this was to study evaluate the effect of relining on the marginal accuracy of ceromer crowns. material and methods: one ivorine maxillary central incisor was prepared for targis crown. 10 acrylic models were duplicated fr...
