Color constancy and hue scaling.
In this study, we used a hue scaling technique to examine human color constancy performance in simulated three-dimensional scenes. These scenes contained objects of various shapes and materials and a matte test patch at the center of the scene. Hue scaling settings were made for test patches under five different illuminations. Results show that subjects had nearly stable hue scalings for a give...
متن کاملEfficient intensity-hue-saturation-based image fusion with saturation compensation
Te-Ming Tu Shun-Chi Su Hsuen-Chyun Shyu Ping Sheng Huang Chung Cheng Institute of Technology Department of Electrical Engineering Taoyuan, Taiwan 33509 Republic of China Abstract. The intensity-hue-saturation (IHS) and Brovey transforms are two widespread image fusion methods in the remote sensing community. However, both are sensitive to the characteristics of the analyzed area. Restated, they...
متن کاملEffect of Color Saturation and Hue on Image Quality
In this paper, it will be shown that the effect of color saturation and hue on image quality can be described in a very simple way. From measurements given in this paper it appears that there is a remarkable agreement between color saturation and gamma with respect to their effect on image quality. From an earlier investigation it was found that image quality increases with the square root of g...
متن کاملThe prediction of hue and saturation for non-spectral lights
The Jameson and Hurvich opponent-colors model of hue and saturation was tested for spectral and non-spectral lights. Four observers described the color of lights by scaling hue and saturation. The lights ranged from 440 to 640 nm and consisted of five purities: 1.0, 0.80, 0.60, 0.40 and 0.20. Admixtures of monochromatic and a xenon-white light yielded the different colorimetric purities. For ea...
متن کاملThe Taming of the Hue, Saturation and Brightness Colour Space
The transformation of the RGB colour space to a hue, saturation and brightness colour space is essentially a conversion from a rectangular coordinate system to a cylindrical coordinate system. Nevertheless, a bewildering array of such conversions exist. We show that one of the main reasons for this is the dependence of the saturation values on the choice of the brightness function, and suggest ...
