【摘要】 基于颜色特征的分析在计算机视觉分析系统中占有非常重要的地位。对于同一被摄对象,当光照条件或成像设备发生变化时,得到的图像颜色数据会发生相应的变化。如何在光照或成像设备改变的情况下,实现图像颜色数据的复原是计算机视觉分析系统中关键技术。本文将色彩管理的概念引入到分析系统图像的颜色复原中,提出了基于ICC特征描述文件的颜色复原方法,实现了不同设备环境下得到的图像颜色向标准环境下颜色数据的转换。更多还原

【Abstract】 Color character analysis plays an important role in the computer vision system. For an object captured by the system, with the changes in the imaging device or the illumination condition, the color of the image will change accordingly. It’ s critical for computer vision analysis system to obtain consistent color under different situation. The color management method is adopted and an ICC standard based color reproduction approach is presented here so that the color of images captured under different situation could be translated into the color under the standard condition which has been defined in advance.更多还原
