基于多项式回归法的显示器色彩空间转换模型研究

彩色显示器是用来传达颜色的重要工具,而色彩在不同设备和系统上往往会有差异,所以建立一个显示器色彩管理系统很有必要.用色彩管理软件及分光光度仪对显示器进行屏幕的校准和特性化,采用多项式回归算法建立了CIE RGB到CIE XYZ颜色转换模型,并对转换模型所得到的X,Y,Z计算值与实际测量值进行比较,取得了较好的实验结果.模型转换后的绝大部分色差都小于6,在人的视觉不敏感范围内,故转换模型具有较高的转换精度.

Research on the display color space conversion model based on polynomial regression method

Color LCD is an important tool to communicate, and colors in different equipment and systems often make difference, so the establishment of a color management system is necessary to display. Calibration and characteristics of color management software is used and spectrophotometer screen is applied to display, the polynomial regression algorithm has been established the CIE RGB to CIE XYZ color conversion model, and the transformation model are X, Y, Z calculated values are compared with the actual measured value. Good results are achieved that the most color difference after model transformation is less than 6, which is not sensitive to the human visual range. Conversion model is proved to have higher accuracy.
