Hue discrimination, unique hues and naming.
The hue discrimination curve (HDC) that characterizes performances over the entire hue circle was determined by using sinusoidally modulated spectral power distributions of 1.5 c/300 nm with fixed amplitude and twelve reference phases. To investigate relationship between hue discrimination and appearance, observers further performed a free color naming and unique hue tasks. The HDC consistently...
متن کاملNo difference in variability of unique hue selections and binary hue selections.
If unique hues have special status in phenomenological experience as perceptually pure, it seems reasonable to assume that they are represented more precisely by the visual system than are other colors. Following the method of Malkoc et al. (J. Opt. Soc. Am. A22, 2154 [2005]), we gathered unique and binary hue selections from 50 subjects. For these subjects we repeated the measurements in two s...
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...
