摘要
本文深入分析了彩色复制过程中造成阶调失真的主要原因,重点阐述了颜色传递过程中引入误差的影响。将颜色传递过程分解为色域映射和色空间转换两大类算法,首先对色域映射边界的描述以及基于图像的色域映射算法的选择问题进行了分析;对色空间转换常用的三种算法,即多项式回归、神经网络和三维插值等算法进行了对比和分析,并列举了当前这一领域的研究现状和今后的发展方向。
In this paper,the key reasons of color distortion in color printing were introduced,and the errors generated in color transmission were mainly analyzed.The color transmission process was divided into gamut mapping and color conversion. Firstly the gamut boundary description algorism and choosing algorithm of gamut mapping based on image were analyzed, and then three color conversion methods including polynomial regression,neural network and 3D interpolation were compared. Finally the status and development were listed.
