Coding efficiency of CIE color spaces
Estimates were made of the efficiency with which color spaces code color information from images of natural scenes. Six spaces were tested, namely, CIE XYZ tristimulus space, and the spaces CIELUV, CIELAB, CIELAB and S-CIELAB after chromatic adaptation with CMCCAT2000, and the space CIECAM02. For each space, the information available and the information retrieved in color matching were calculat...
متن کاملCIE Work in Color Imaging
The CIE Board of Administration has proposed a new Division to study procedures and prepare guides and standards for the optical, visual and metrological aspects of the communication, processing, and reproduction of images, using all types of analogue and digital imaging devices, storage media and imaging media. While current practice enables adequate color communication within single industrie...
متن کاملUniform color spaces and natural image statistics.
Many aspects of visual coding have been successfully predicted by starting from the statistics of natural scenes and then asking how the stimulus could be efficiently represented. We started from the representation of color characterized by uniform color spaces, and then asked what type of color environment they implied. These spaces are designed to represent equal perceptual differences in col...
متن کاملUniform Color Spaces: 3D LUTs vs. Algorithms
Until recently I have always used L*a*b* as a very convenient tool to transform color data into a sensible isotropic color space. Since isotropic spaces are uniform in all directions, the space performed the difficult task of making sure that differences in hue, lightness and chroma were all taken into account and that any pair of equal distances between two colors, regardless of their location...
متن کاملRotation Invariant Color Texture Classification in Perceptually Uniform Color Spaces
* * * b a L is a perceptually uniform color space and HSV approximately perceptually uniform space for representing color. But commonly used color space is RGB, which is not perceptually uniform. In this work we compare these three-color spaces for rotation invariant color texture classification. The inclusion of color aspects of texture in image processing is increasing rapidly. Gabor wavelets...
