针对传统亮度参数Y与视觉感受不够吻合的现象,利用CIEDE2000均匀色差标准与主观视觉感受较为吻合的特点,从CIEDE2000均匀色差标准中的主观亮度参数L’入手,建立了基于CIEDE2000均匀色差标准的亮度测试图像设计方法。通过与传统亮度参数y的实验结果进行比较,可以发现基于CIEDE2000均匀色差标准设计的亮度测试图像与视觉感受具有较好的线性关系,对于实现与主观评价结果相吻合的彩色图像质量评价系统有重要意义。
To investigate the effect of luminance parameters of color image on subjective visual, this paper establishes a luminance test image signal design method based on subjective luminance parameters L' of CIEDE2000. The luminance test images designed by the present method are experimentally shown fitting the subjective visual perceptional very well. The present work may prove the road towards the establishing of a color image quality assessment system consistent with the subjective assessment results.
