In commercial point of view, it is of great interest to find colors with high color constancy level. Color constancy as a relatively property of object’s appearance could be affected by different factors. In this article, the color inconstancy index of CMCCON02 and CIELAB color coordinate of 1269 samples of Munsell at CIELchº color system to study any correlations, was calculated. The correspon...

The use of metamerism index & color inconstancy index is studied for approval of spot colors used in decorative gravure products, especially spot colors, which are viewed under different light sources at the customer’s end. This work shows that the metamerism index is not sufficient for approval of spot colors, because it doesn’t provide any idea about how colors will transform under different ...

The color inconstancy of prints is related to the ink spectral properties and the lookup table for multiink printing systems. In this paper, color inconstancy was investigated for several ink-jet printers based on their ink set and the default lookup tables. A virtual model for each printer was created to determine the range of color inconstancy that a specific ink set could achieve. The color ...

A computer simulation was performed to investigate optimal fourand five-ink sets in order to minimize color inconstancy while maintaining a large color gamut. The effect of including a spectrally-flat black ink on color constancy was explored. The relationship between ink shape and the color constancy of prints was also analyzed. The results show that the ink shape in the middle wavelength regi...

The rationale, formulae, and examples for assessing the color inconstancy of consumer digital cameras are pre­ sented. Its use is appropriate for evaluating the color/neutral balance precision of consumer digital camera systems with respect to illumination quality; specifically for a given rendering intent such as sRGB or ROMM. Adopting the ∆E94* color difference measure, an extended color inco...

Color constancy is something we take for granted. An apple appears red despite monumental changes in the intensity and spectral balance of illumination. There are many components to human visual system that make this illusion possible. Nonetheless, imperfect. Objects will change apparent color under different The CIELAB space allows computation values any illuminant. will, general, as illuminan...

In this paper, a novel moving object modeling suitable for multicamera correspondence is introduced. Taking into consideration the color and motion features of foreground objects in each independent video stream, our method segments the existing moving objects and constructs a graph-based structure to maintain the relational information of each segment. Using such graph structures reduces our c...

In order to study large variations or fluctuations of finite or infinite sequences (time series), we bring to light a 1868 paper of Crofton and the (Cauchy-)Crofton theorem. After surveying occurrences of this result in the literature, we introduce the inconstancy of a sequence and we show why it seems more pertinent than other criteria for measuring its variational complexity. We also compute ...
