论文摘要
我们提出了一种具有最佳传输（OT）的新色转移方法，以传递源图像的颜色，以匹配同一场景的目标图像的颜色，该目标图像可能在图像之间显示出较大的运动变化。根据定义，ot在计算最佳解决方案时未考虑有关对应关系的任何可用信息。为了解决这个问题，我们建议使用使用运动估计估算的颜色和空间对应关系编码像素的重叠邻域。我们使用迭代投影方法在1D空间中解决了高维问题。我们进一步引入了平整介绍，作为解决最佳传输（即迭代分布电网（IDT））及其变体切片的Wasserstein距离（SWD）的迭代算法的一部分。实验表明，与先前的艺术色传递方法相比，定量和定量改进。
We propose a new colour transfer method with Optimal Transport (OT) to transfer the colour of a sourceimage to match the colour of a target image of the same scene that may exhibit large motion changes betweenimages. By definition OT does not take into account any available information about correspondences whencomputing the optimal solution. To tackle this problem we propose to encode overlapping neighborhoodsof pixels using both their colour and spatial correspondences estimated using motion estimation. We solvethe high dimensional problem in 1D space using an iterative projection approach. We further introducesmoothing as part of the iterative algorithms for solving optimal transport namely Iterative DistributionTransport (IDT) and its variant the Sliced Wasserstein Distance (SWD). Experiments show quantitative andqualitative improvements over previous state of the art colour transfer methods.
