Extraction of Non-Linear Components from 3D- & LUT In ICC Profiles and Re-composition of New Profile for Better Color Reproduction
نویسندگان
چکیده
Color conversion model used in ICC specification is based on multi-dimensional look-up table and linear interpolation. This color conversion model is useful for device independent color reproduction. But in order to get a high spaed of color conversion for large image data, this interpolation needs simple calculation process. If non-linear interpolation smoothness will become better than simple calculation method. We tried re-composition of 3D-LUT to bigger three dimensional lookup table by non-linear interpolation before image conversion by linear interpolation, and explain its process and evaluated results.

The Creation of the sRGB ICC Profile
This paper describes transforming the sRGB color space standard into an ICC profile. This sRGB ICC profile provides a clear bridge between implicit color management and explicit color management and illustrates the complementary nature of these two approaches. The paper starts by reviewing the current status and content of the sRGB color space standard. It also very briefly reviews the status o...
متن کاملEvaluating the Use of the Perceptual Reference Medium Gamut in ICC PrintingWorkflows
The International Color Consortium (ICC) specifies a standard profile format and associated color management architecture. In the version 4 of its specifications, it adopted a Perceptual Reference Medium and an associated gamut (PRMG) for perceptual workflows. The goals of this change were improved interoperability and more pleasing results. In this paper we start evaluating the effect of using...
متن کاملA Generalized Linear Statistical Model Approach to Monitor Profiles
Statistical process control methods for monitoring processes with univariate ormultivariate measurements are used widely when the quality variables fit to known probabilitydistributions. Some processes, however, are better characterized by a profile or a function of qualityvariables. For each profile, it is assumed that a collection of data on the response variable along withthe values of the c...

Software developers have created applications that can build custom device profiles that conform to the standards established by the International Color Consortium (ICC). These software applications must address several color reproduction issues during the construction of an ICC device profile. The color reproduction issues could be controlled by input from the person building the profile or by...
