Constructing uniform color space in CIECAM97s

摘要

＜正＞ The uniformity of two pairs of color spaces based on CIE 1997 color appearance model （CIECAM97s） is analyzed according to color-discrimination ellipses that are constructed using color-difference evaluation data. A new uniform color space named Jucs aucs bucs deduced by re-scaling the coordinates of lightness, redness-greenness and yellowness-blueness in two initial color spaces using linear regression method. The uniformity of the new color space is obviously improved compared with the initial color spaces.
