Novel workflow for image-guided gamut mapping
نویسندگان
چکیده
bstract. We introduce a novel workflow that will hopefully open ew directions of processing and improvement in image reproducion. Existing gamut mapping algorithms can be classified into two asic categories: image-independent algorithms and imageependent algorithms. The latter algorithms produce better reprouction; however, because they are time consuming and mathematially complex, the image-independent approach is commonly used n most imaging workflows. We suggest a new workflow that atempts to approach the image-dependent mapping method without ncurring significant computational drawbacks nor requiring changes n the imaging industrial standards. The proposed method attempts o choose an appropriate gamut mapping per image without recontructing the image gamut itself and without constructing an imagepecific mapping on the fly, as required by image-dependent gamut apping methods. Specifically, image characteristics are exploited or selection of a source gamut and a gamut mapping most approriate for a given input image from a set of available mappings. ccordingly the proposed method is named image-guided gamut apping. We show the practicability and advantages of the sugested workflow in several specific cases. We show that better imge quality is achieved for 87% of the tested images when using the uggested workflow. © 2008 SPIE and IS&T. DOI: 10.1117/1.2955996

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 کاملImage-Difference Measure Optimized Gamut Mapping
Even though there is still room for improvement, recent perceptual image-difference measures show a prediction performance that makes them interesting to be used as objective functions for optimizing image processing algorithms. In this paper, we use a color enhanced modification of the Structural Similarity (SSIM) index for optimizing gamut mapping. An iterative algorithm is proposed that mini...
متن کاملImage-dependent three-dimensional gamut mapping using gamut boundary descriptor
A 3-D image-to-device gamut mapping algorithm (I-D GMA) is an ideal way to map display image to the inside of printer gamut. A quick decision whether or not each pixel is located inside of the device gamut is necessary to execute a 3-D I-D GMA. We propose a new gamut boundary descriptor (GBD) for comparing the gamut between image and device by the discrete polar angle (Du,Dw). The gamut shell i...

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...
