基于颜色融合的交互式图像二次着色方法*

针对灰度图像彩色化技术应用于彩色图像二次着色时往往忽略掉原始图像所带的色彩信息的问题，提出了一种基于最短距离颜色融合的交互式彩色图像二次着色方法，通过有效利用原始图像中的色彩信息降低用户交互复杂度。计算过程中采用分层采样与随机采样相结合的策略，确保种子像素合理分布，在颜色融合过程中增加动态权值调整，减少笔画位置对着色结果的影响。实验结果说明该方法与现有颜色扩展着色方法相比较，其结果不再过度依赖于初始用户标记的位置，不需要用户进行复杂的彩色线条标记就能够得到不错的着色效果。

Interactive image recolorization based on chrominance blending

It is possible to recolorize images by applying existing scribble based colorization algorithms for grayscale images,which omitting colors in original images.This paper presented a novel intrinsic-distance-based recolorization technique using chrominance blending.It required less manual effort by taking full advantage of the original image.The scribbles were well relocated by propagating the user adjustments.And the dynamic weights adjusting policy for blending were explored which made the colorization resu...
