扫描输入数据的颜色校正
Color Correction of Scanning Input Data

摘要: 提出了RGB子空间的概念,并在RGB子空间内使用最小二乘原则建立从设备RGB空间直接到CIELAB空间的三维一阶映射方程,实现了对扫描输入数据的颜色校正。通过试验验证,理想色与分别在各RGB子空间内建立的颜色映射方程所计算颜色的色差明显小于与在整体空间建立的映射方程所计算颜色的色差。Abstract: On the basis of the concept of RGB subspace developed in this paper, we purpose that the whole RGB space should be divided into some RGB subspaces;thus in the subspaces the three dimensional one-order transferring function can be deduced by using LSM from the device RGB space to CIELAB space directly.This method can be used in color correcting for scanning input data.
