摘要
采用Newton-Raphson算法建立了美国光学学会均匀颜色标尺系统的反向模型,对反向模型算法的精度进行了验证.结果表明,反向模型能够满足实际生产的精度要求.反向转换模型的建立弥补了均匀颜色标尺系统的不足,同时在Matlab环境下,对CIELAB,CIELUV,CIECAM97s,IPT和CIECAM02等5个常见颜色空间的视觉均匀性作了比较分析.研究表明,IPT和CIECAM02颜色空间在颜色视觉均匀性方面具有优良的性能.这对于颜色复制工业中色貌模型的正确选择有着重要的意义.
The inverse transformation model of the uniform color scales of the optical society of America （OSA-UCS） has been made using the Newton-Raphson algorithm. The accuracy of the inverse model is assessed using the data. The result shows that the inverse model can meet the needs of the practical application. The realization of the inverse model is of great complement for the OSA-UCS. The data for different color space such as CIELAB, CIELUV,CIECAM97s,IPT and CIECAM02 are compared with the help of the matlab. The result shows that the IPT and CIECAM02 has optimum performance in the visual uniformity. It has a great reference value in the choice of color appearance model for the color reproduction industry.
