为了将彩色图像转换为单色图像，在HDTV标准中像素的亮度分量被用作表示单色图像的灰度级。然而，仅嵌入色度分量的图像的显着性在使用亮度分量转换的单色图像中消失。为了解决这个问题，A.A.古奇等人。提出了保留显着性的颜色去除方法ldquoColor2Gray。ldquo 在本文中，首先分析了Color2Gray 并揭示了其数学性质。然后，利用该数学性质提出了快速Color2Gray算法。最后，通过实验证明了所提算法的有效性。
In order to convert a color image into a monochrome one, luminance components of the pixels have been used as gray-levels for the representation of the monochrome image in HDTV standard. However, saliencies of the image embedded only in the chrominance components are disappeared in the monochrome image converted by using luminance components. To cope with this problem, A.A. Gooch et al. have proposed the salience-preserving color removal method called ldquoColor2Gray.ldquo In this paper, at first, Color2Gray is analyzed and its mathematical property is revealed. Then, fast Color2Gray algorithm is proposed by use of the mathematical property. Finally, some experiments prove the effectiveness of the proposed algorithm.
