传统分割算法考古来到了最后一章,这次要讲的是一个非常有趣有用的免训练、可交互的图像分割算法——Graph Cut 图分割。原论文为: Interactive Graph Cuts for Optimal Boundary & Region Segmentation of Objects in N-D Images [1] 我将这个玩具写成了一个200行代码内就能在网页中打开的应用(代码在文章最后的附...

1、GraphCut介绍 GraphCut是图论分割方法之一,而图论方法把图像分割问题与图的最小割(min cut)问题相关联。首先将图像映射为带权无向图G=<V,E>,图中每个节点N∈V对应于图像中的每个像素,每条边∈E连接着一对相邻的像素,边的权值表示了相邻像素之间在灰度、颜色或纹理方面的非负相似度。而对图像的一个分割S...
