在多媒体内容中，颜色在传达视觉信息方面起着重要作用。然而，颜色信息并不总是被所有人均匀地感知。有色觉缺陷的人，如色盲，不能识别和区分某些颜色组合。本文提出了一种有效的亮度修改方法，该方法可以使具有正常色觉的人，特别是原盲或绿盲的人的无障碍色觉，同时保留原始图像中的颜色信息。在所提出的方法中，首先定义一个优化问题的亮度分量考虑在输入图像中的颜色差异。然后，通过求解优化问题，获得了一个可感知的和可理解的彩色图像的protanopes和观众没有色觉缺陷或deuteranopes和观众没有色觉缺陷。通过实验验证了该方法的有效性。
In multimedia content, colors play important roles in conveying visual information. However, color information cannot always be perceived uniformly by all people. People with a color vision deficiency, such as dichromacy, cannot recognize and distinguish certain color combinations. In this paper, an effective lightness modification method, which enables barrier-free color vision for people with dichromacy, especially protanopia or deuteranopia, while preserving the color information in the original image for people with standard color vision, is proposed. In the proposed method, an optimization problem concerning lightness components is first defined by considering color differences in an input image. Then a perceptible and comprehensible color image for both protanopes and viewers with no color vision deficiency or both deuteranopes and viewers with no color vision deficiency is obtained by solving the optimization problem. Through experiments, the effectiveness of the proposed method is illustrated.
