摘要
从RGB颜色空间入手,在对现有的几种RGB色差度量公式分析对比的基础上,总结出RGB颜色色差的3个基本规律,提出颜色分量的重要程度这一概念。并根据颜色分量的重要程度用动态系数调整RGB颜色间的空间距离和矢量角度值,从而得到了一种全新的RGB颜色空间的色差度量公式。通过高复杂度图像的颜色量化实验证明该色差公式在颜色量化中的性能优于目前使用较为广泛的几种RGB色差度量公式。
Based on the study of RGB(red-green-blue) color space and the comparison and analysis of several color difference formulas in RGB color space,this paper summarized three rules of color difference in RGB color space and proposed the conception of the importance of the color component.A new color difference formula in RGB color space was achieved by dynamically adjusting the vector distance and angular between a pair of RGB colors.The dynamic coefficient was weighted by the importance of color component.Color...
