摘要
目的研究CIECAM02和iCAM色貌模型颜色空间的均匀性,以及应用于不同观察条件下的图像复制效果。方法利用均匀颜色数据集测试色貌模型颜色空间的均匀性,并通过视觉评价实验来测试2个色貌模型的图像复制效果。结果 CIECAM02的色貌空间具有更好的色差均匀性,iCAM的色貌空间具有更好的色相、明度和彩度均匀性。在不同观察条件下的图像复制中,CIECAM02有更好的表现。结论iCAM的颜色空间适合于颜色色貌属性的计算,而CIECAM02的颜色空间更适合于颜色色差的计算,在不同观察条件下的图像复制中,CIECAM02有更稳定的表现,但并不是对所有图像都有更好的表现。
The work aims to investigate the uniformity of color space of CIECAM02 and iCAM and the effect of im-age reproduction applied in different viewing conditions. The uniform color data sets were used to test the color space uniformity of color appearance models, and the visual evaluation experiments were conducted to test the image reproduc-tion effect of two color appearance models. The results showed that the color appearance space of CIECAM02 per-formed better in color difference, and the color appearance space of iCAM performed better in hue, lightness and chroma uniformity. CIECAM02 performed better in image reproduction under different viewing conditions. The color space of iCAM is suitable for calculating color appearance attributes, while the color space of CIECAM02 is more suitable for color difference calculation. In the image replication under different viewing conditions, CIECAM02 has a more stable performance, but it is not better for all the images.
