中国国画计算机色彩还原系统的研究

专家指出,自古至今书画文物复制仍然是保护文物的一项重要手段.其中珍贵名书画的色彩还原是其重点.本研究针对中国国画常用颜料色彩特性及国画色彩老化现象,利用计算机数字图像处理技术,色彩学理论在Windows XP环境中使用Visual C .NET编程,构筑中国国画计算机色彩还原原型系统.为国画色彩还原提供了常用的色阶、亮度/对比度、色彩平衡、曲线调节之外,还研发了基于HSV色彩空间的国画常用色彩还原,以及指定任意色域的色彩还原微调系统.经专业人员试验,达到了较好的计算机国画色彩还原效果.

Computer color recovery system for traditional Chinese painting

In all ages,repairing of cultural relic is an important way to protect cultural relic.And the color recovery is the key point to those costly rarity painting and calligraphy.This letter is based on research of traditional Chinese painting's pigments and color aging model,use computer digital image manipulation technology and chromatics to create a color recovery system for traditional Chinese painting.The tool we used is Visual C .NET,and the platform is Windows XP.The system provide conventional color adjusting function,such as color levels,brightness and contrast,color balance,curves,etc.And it also contains a new adjusting function,which is exactly aiming at traditional Chinese painting.It can recover the colors used to paint traditional Chinese painting or a random color region in whole color space.By professional testing,this system is efficiency on color recovery of traditional Chinese painting.
