【摘要】 通过使用分光光度计的色度测量,并借助于MATLAB的凸壳函数计算出ICC标准的4种再现意图下的色域体积,同时采用视觉评价方法对图像输出质量进行评价,数据分析与视觉评价的结果,表明了再现意图对于数字印刷图像质量的影响,也表明了色度评价在图像质量评价方面的不足。实验结果对于阐释再现意图、色域体积和图像质量3者之间的关系和对印刷图像质量的科学评价具有参考意义。更多还原

【Abstract】 Based on the results obtained by spectrophotometer measurements,the gamut volumes of ICC standard rendering intents were calculated with the convex hull function in MATLAB.At the same time the visual evaluations were applied to evaluate the output image quality.The data analysis in relation to the results of visual evaluations showed the difference influence of the rendering intents on digital image quality and the insufficient of using chroma to decide the image quality.The results can be significant for explaining the relationships of gamut volume,rendering intent,and the image quality in digital printing,and for the scientific evaluation to image quality.更多还原
