This paper is aimed to the determination of optical pseudogap values in phases with argyrodite structure by a simple method diffuse reflectance spectroscopy. Samples (Cu1-xAgx)7PSe6 (x = 0, 0.2, 0.3, 0.4, 0.6, 0.7, 0.9, 1.0) solid solutions were obtained form microcrystalline powders grinding agate mortar. The spectra samples studied spectral range 220–1400 nm (293 K) and analyzed using Kubelka...

This theory was originally developed for paint films but works quite well in many circumstances for paper. It is not, however, terribly good for dyed papers (or very dark, unbleached papers) when light absorption reaches a high level. A limiting assumption is that the particles making up the layer must be much smaller than the total thickness. Both absorbing and scattering media must be uniform...

In this paper, we present an empirical approach for rendering realistic watercolor effects in real-time. While watercolor being a versatile media, several characteristics of its effects have been categorized in the past. We describe an approach to recreate these effects using the Kubelka-Munk compositing model and the Sobel filter. Using modern per-pixel shading hardware, we present a method to...

ÐThis paper presents the measurement of colored object reflectance, under different, general assumptions regarding the imaging conditions. We exploit the Gaussian scale-space paradigm for color images to define a framework for the robust measurement of object reflectance from color images. Object reflectance is derived from a physical reflectance model based on the Kubelka-Munk theory for color...

Object-oriented programming aims to facilitate navigation between domain concepts and the code that addresses those domains by enabling developers to directly model those domain concepts in the code. To make informed decisions developers then formulate detailed and domainspecific questions about their systems in terms of domain concepts, and use tools to explore available information and answer...

an algorithm is suggested for implementation of unlimited primaries in two-constants kubelka-munk color matching attempt. allens method for tristimulus color matching which was limited to four colorants in two constant theory, dealt with inversable matrices. by application of the pseudo-inverse, it is not necessary to limit the number of primary colors to four as allen suggested. the suggested ...
