基于加权视觉色差的三维色域匹配算法
Three-dimensional GMA based on weighted visual color difference
【摘要】 提出了以加权视觉色差为评价标准的三维色域匹配算法。加权视觉色差公式由C IE 1994色差公式引申而出,根据权重系数在色差边界的GBD矩阵内确定了动态的空间搜索范围,将重心坐标方程应用于搜索值并得到最终匹配结果。通过基于相纸色域的仿真实验,验证了三维色域匹配在视觉感知和色差方面都要优于传统的二维匹配。
【Abstract】 A three-dimensional GMA(gamut mapping algorithm) in which the weighted visual color difference acted as the evaluating criterion was proposed.This color difference equation was educed by CIE1994 color difference equation and its weight coefficients decided the dynamic searching space in GBD(gamut boundary descriptor) matrix.Then applying barycentric coordinate equation on the gotten GBD points,the mapping results were calculated. Simulation based on printing paper′s gamut show that both the visual sense and color difference results in three-dimensional gamut mapping are better than that in two dimensional gamut mapping.
【Key words】 three-dimensional gamut mapping; weighted visual color difference; barycentric coordinate;
