GRABCUTOpenCV中的GrabCut算法是依据《"GrabCut" - Interactive Foreground Extraction using Iterated Graph Cuts》这篇文章来实现的。该算法利用了图像中的纹理（颜色）信息和边界（反差）信息，只要少量的用户交互操作即可得到比较好的分割结果。如果前景和背景之间的颜色反差不大，分割的效果不好；不过，这种情况下允许手工标记一些前景或背景区域，这样能得到较好的结果。-GRABCUTOpenCV in GrabCut algorithm is based on the " "　GrabCut " - Interactive Foreground Extraction using Iterated Graph Cuts"　in this article to achieve. The algorithm uses the image texture (color) and the boundary information (contrast) information, as long as the amount of user interaction to obtain a better segmentation results. If the color contrast between foreground and background is not, split ineffective　however, allow manual marking some of the foreground or background areas, this can get better results in this case.
