摘要
首先用OTSU方法将目标图像和参考图像递归分解成对应的若干个相对均匀的区域,这些区域的类间距较大而类内距较小;然后将对应的区域之间进行颜色线性变换.由于没有使用全局统计信息,因而具有较强的通用性.实验结果表明:文中算法的颜色传输效果良好,适用性强,且能在相似性较差的图像间进行颜色传输.
The current color transfer methods always use statistics as transfer function and can not deal with images with lower similarity. In this paper, a section by section color transfer method is presented, in which all the source images and reference images are segmented into a series of homogeneous regions, in which variations between classes are big and variations within classes are small, and then the color between the corresponding regions are transferred. The experiments show that the algorithm is efficient, the results are satisfactory, and it can be applied to complicated images with lower similarity.
