图像之间的颜色传输有效地利用了图像的基本统计信息，该文提出了一种基于图像的简单统计信息和梯度域信息的局部颜色迁移算法.算法提供了简单易用的操作界面，用户可以画线来指定对应的局部区域；由于采用了图像自身的梯度域信息，颜色迁移过程可以很好的保持源图像的颜色细节；还可以简单推广到灰度图上色问题，有效提高了灰度图上色速度.各种实验结果表明，该算法较好的实现了源图像和目标图像的局部区域颜色对应，可以方便而有效地表达用户的意图，生成具有较好视觉效果的真实自然的新图像.-Color transfer between images use the statistics information of image effectively. In this paper, we present a novel approach of local color transfer based on the simple statistics and gradient domain information of images. A sketching interface is proposed for quickly and easily specifying the color correspondences between source and target image. The user can specify the correspondences of local region using scribes. Owing to adopt the gradient of image, our approach can preserve the color details of source image, and can extends to colorization problem naturally for sake of improving the speed of colorization. Various experimental results show that our approach can specify the correspondences of local color region in source and target image, can express the intention of users, and generates actual and natural results for visual effect.
