Printing with custom inks is useful for extending the gamut of printed images, for creating artistically appealing designs or for providing protection against counterfeiting (security documents). The basic colors we consider, consist of the custom inks, their superpositions and the white paper. Color separation for custom inks requires to determine the relative amounts of the basic colors allow...

creating and preserving large patches in land use configuration and satisfying compactness and contiguity in land use configuration are nature-prescribed and nature-inspired criteria that can be used in land use planning better that before. accompanying compactness and contiguity as the important landscape metrics in land use planning and land use configuration is close to applying proactive ap...

The aim of this work is the evaluation of Multivariate Gaussian Mixture Model (MGMM) in different color spaces (RGB, L*a*b* and YC1C2 issued from IHLS). We have analyse the approach for the description of the color information in an image in the one hand and for the representation of a color image in the other hand. To achieve this goal we need an accurate estimation method of MGMM parameter se...

The purpose of this study was to investigate differences between natural tooth color and that selected for artificial teeth in partial dentures at our department with a view to establishing criteria for obtaining greater harmonization between colors. The participants in this study comprised partial denture wearers visiting the Department of Prosthodontics, Tokyo Dental College Chiba Hospital, i...

We develop a new method to identify YSOs from star-forming regions using the photometry data from Spitzer’s c2d Legacy Project. The aim is to obtain YSO lists as complete as possible for studying the statistical properties, such as Star Formation Rate (SFR) and lifetimes of YSOs in different evolutionary stages. The largest obstacle for identifying YSOs comes from background galaxies with simil...

The work is devoted to the problem of comparing objects by color. following statement considered: among set it necessary find such an object, color which most similar given object. It assumed that for each object only its spectrum (transmission, reflection, radiation) known, exhaustive characteristic In addition, radiation source be known. use standard methods determining differences has shown ...

We address a bicriterion path problem where each arc is assigned with a cost value and a label (such as a color). The first criterion intends to minimize the total cost of the path (the summation of its arc costs), while the second intends to get the solution with a minimal number of different labels. Since these criteria, in general, are conflicting criteria we develop an algorithm to generate...

The majority of color work in machine vision has been based on a trichromatic (and specifically RGB) color representation. In reality, color is a continuous univariate function of wavelength which can be quantized into an arbitrary number of dimensions. The capture of reflectance information in spectrally higher dimensions will improve image analysis. To acquire spectrally and spatially highdim...

In this paper we explore the possibility of capturing color trends and understanding the rationale behind the popularity of a color. To this end, we propose using a preference disaggregation approach from the field of MultiCriteria Decision Analysis. The main objective is to identify the criteria aggregation model that underlies the global preference of a color. We introduce a new disaggregatio...
