“…is the color coordinates of a large object in a test image and Adam, 1974); o u = 0,201 and o v = 0,307 is the chromaticity coordinates of basic white color. When comparing color fields located in "window" on a neutral background one can notice, that color differences (1) are invisible at 3 2... ≤ ε (MPCD) for the whole color space which is explained by the properties of equal color spaces (Novakovsky, 1988).…”

“…In addition to having certain optical properties, the coating should withstand exposure to the high temperatures reached with induction stoves (above 400 °C) without the optical properties of the coating being altered to such a degree that a change in the coating color can be visually detected [20,21].…”

This paper introduces a thin film multilayer structure composed of dielectric and metallic layers that allows for a wide range of aesthetic appearances using the phenomenon of optical interference. In addition, this multilayer structure allows the reflection and transmission coefficients to be controlled independently. The application of these decorative coatings to induction stoves is also studied. The aim is to provide an attractive aesthetic appearance for the transparent glass-ceramic, and allow the visualization of blue and white lighting systems. Moreover, degradation of these decorative coatings is studied at high temperatures, so as to ensure that the coating does not change its aesthetic appearance during normal operation of the stove. It has been found to be necessary to use dielectric materials with low diffusion coefficients of oxygen, or not containing oxygen, to prevent oxidation of the metal layers when subjecting the coating to high temperatures.

“…Usui et al constructed a fivelayer BP neural network and generated an identity mapping of the surface spectral-reflectance data of 1280 Munsell color chips, using a back-propagation learning algorithm [5]. Fairman et al applied PCA to several databases [6][7][8]. In 2006, according to the ten hues fitted to Munsell database by Cohen [9], Ayala et al divided the color space into ten zones [10].…”

Compared with tristimulus, spectrum contains much more information of a color, which can be used in many fields, such as disease diagnosis and material recognition. In order to get an accurate and stable reconstruction of spectral data from a tristimulus input, a method based on locally linear approximation is proposed in this paper, namely SR-LLA. To test the performance of SR-LLA, we conduct experiments on three Munsell databases and present a comprehensive analysis of its accuracy and stability. We also compare the performance of SR-LLA with the other two spectral reconstruction methods based on BP neural network and PCA, respectively. Experimental results indicate that SR-LLA could outperform other competitors in terms of both accuracy and stability for spectral reconstruction.
