| 中文摘要: |
| 目前色域映射多在二维色相平面上进行,色域描述相应地转换为色调剖面上的边界线描述。 通过分析打印机色调剖面边界形状,结合考虑色域映射的精度和效率问题,提出了运用带插值条件的最小二乘模型分段拟合打印机色域边界。 实验结果表明:该技术的运用可以确保打印机色域边界的连续性,同时拟合效果也与分段线性插值方法很接近,从而保证了色域映射的精度,其最大的优势是提高了色域映射的效率,使色域映射的实施更加简单。 |

| Now gamut mapping is usually implemented on two dimensional color planes, accordingly the gamut description is converted to the boundary description on hue profile. A method with least squares interpolation condition to fit the gamut boundary line piecewise was put forward through analysis of boundary shape and considering the accuracy and efficiency of gamut mapping. The result showed that the method can ensure the continuity of the gamut boundary; the fitting effect is close to that of piecewise linear interpolation method, which ensure the accuracy of gamut mapping; the greatest advantage of this method is the improvement of gamut mapping efficiency, which simplify gamut mapping. |
