摘要

近年来,随着媒体设备的发展,彩色图像被广泛应用于各个领域。然而,具有二色性或异常三色性视觉的人很难分辨普通三色性视觉所能分辨的颜色。为了改善二色性患者的图像可视性,本研究提出了一种考虑色度损失的亮度修正方法。首先,定义了双色人的色度损失。随后,构建了包含色度损失的目标函数。为了关注色度损失较大的颜色对,在目标函数中引入了权重。然后对目标函数进行最小化,以获得输出图像。最后,通过实验验证了所提方法的有效性,实验结果表明,所提方法可以保持正常三色人的自然度,并提高二色人的识别率。

Lightness modification method considering chromaticity loss for dichromats

Lightness modification method considering chromaticity loss for dichromats

In recent years, with the development of media equipment, color images have been extensively applied in various domains. However, people with dichromatic or anomalous trichromatic vision have difficulty discriminating the colors that common trichromatic vision would distinguish. To improve image visibility for dichromats, a lightness modification method considering the chromaticity loss was proposed in this study. First, the chromaticity loss was defined for dichromats. Subsequently, an objective function including the chromaticity loss was constructed. To focus on color pairs with a large chromaticity loss, a weight was introduced into the objective function. The objective function was then minimized to obtain output images. Finally, the effectiveness of the proposed method was verified through experiments, which indicated that the proposed method could maintain naturalness for normal trichromats and improve recognition for dichromats.
