Color Space Conversion via Gamut-Based Color Samples of Printer
Many types of electronic imaging devices are currently available, including color cathode ray tube (CRT) devices, ink jet printers, offset printing devices, thermal transfer printers, and all of these devices utilize devicedependent color spaces for color specification. However, device-dependent color spaces do not relate to an objective definition of color or human color perception. Therefore,...
متن کاملSpace Sensitive Color Gamut Mapping
gamut mapping, retinex algorithm, calculus of variations, robust reconstruction Gamut mapping is a method to modify a representation of a color image to fit into a constrained color space of a given rendering medium. A laser-jet color printer that attempts to reproduce a color image on a regular paper would have to map the photographed picture colors in a given color range, also known as the im...
متن کاملA New Method for Color Gamut Mapping by Genetic Algorithm
To reproduce an image, it is necessary to map out of gamut colors of the image to destination gamut. It is clear that the best color gamut mapping introduces the perceptually closest image to the original one. In this study, a new color gamut mapping is purposed by the aid of Genetic Algorithm (GA). The color difference between the original and mapped images based on S-LAB formula was chosen as...
متن کاملColor Look-Up Table Design for Gamut Mapping and Color Space Conversion
This paper proposes a method for designing a color lookup table (CLUT) that can simultaneously process gamut mapping and color space conversion without any complex computation. After constructing a LUT composed of the scanner and printer gamuts, fictive sample points are uniformly selected in CIELAB space and CMY values computed using gamut mapping. The scanner input RGB image is then converted...
متن کاملColor Gamut Mapping in a Hue-Linearized CIELAB Color Space
Color gamut mapping plays a crucial role in color management. Depending on the application, it is sometimes desirable to perform color gamut mapping by shifting the lightness and compressing the chroma of an out-of-gamut color while preserving the perceived hue of the color. The term Òperceived hueÓ is used to distinguish between the visual sensation of hue and metric hue angle (e.g., CIELAB hu...
