摘要
分析了颜色分区理论,对颜色分区理论产生误差的原因进行了剖析,提出了分区边界以及共享区域的概念和分区边界描述的修正方法,在此基础上确定了判断颜色是否在共享区域内的规则。通过构建多色分色模型对修正算法进行了检验,对进行共享区域判断和不进行共享区域判断进行了比较。分色实验结果表明,分区边界描述修正方法能很好地解决颜色分区理论产生的误差,能进一步提高多色分色模型的精度。
The color subarea theory and the causes of error of color subarea theory were analyzed. The concepts of subarea boundary and sharing area and a modification method called the subarea boundary description were proposed. On the basis of this a judgment rule of whether the color is in sharing area was confirmed. By building multi-color separation model, the modification algorithm was verified. The effect of carrying out sharing area judgment or not were compared. The separation experiment result showed the subarea boundary description method can solve the error problem of color subarea theory, and can further improve accuracy of multi-color separation model.
