چکیده
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 image ‘color gamut’, into the given printer/page color gamut. Most of the classical gamut mapping methods involve a pixel by pixel mapping and ignore the spatial color configuration. Recently proposed spatial dependent approaches for gamut mapping are either based on heuristic assumptions or involve a high computational cost. Note that spatially varying gamut mapping is inherently image dependent.

A 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 image enhancement technique using gamut mapping based on color space division
This paper proposes a gamut mapping algorithm based on color space division for color reproduction of cross media. As each color device has a limited range of producible colors, the reproduced colors on a destination device are different from those of the original device. In order to reduce the color difference between those devices, the proposed method divides the whole gamut into parabolic sh...
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...
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 کاملStudy on the Gamut Mapping Method Based on BP Neural Network
For digital color devices, complex relationship exists between their input image pixel values and the output color chromatic values, gamut mapping between them as well. The linear models are difficult to describe this relationship effectively. In the study, based on BP neural network, a gamut mapping model with micro space sections is proposed. The gamut mapping model maps color from monitor ga...
