Web图像处理之图像分割(三）之图割（Graph cut）分割简单梳理 Graph cuts是一种十分有用和流行的能量优化算法，在计算机视觉领域普遍应用于前背景分割（Image segmentation）、立体视觉（stereo vision）、抠图（Image matting）等。此类方法把图像分割问题与图的最小割（min cut）问题相关联。 WebGrabCut. 按论文原文的说法，GrabCut在上述graph cut基础之上的改进包括：将基于灰度分布的模型替换为高斯混合模型（Gaussian Mixture Model，GMM）以支持彩色图片；将能一次性得到结果的算法改成了『强大的』迭代流程；将用户的交互简化到只需要框选前景物体即 …

http://html.rhhz.net/buptjournal/html/20240308.htm In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the partition. These edges are said to cross the cut. In a connected graph, each cut-set determines a unique cut, and in some cases … See more A cut C = (S,T) is a partition of V of a graph G = (V,E) into two subsets S and T. The cut-set of a cut C = (S,T) is the set {(u,v) ∈ E u ∈ S, v ∈ T} of edges that have one endpoint in S and the other endpoint in T. If s … See more A cut is maximum if the size of the cut is not smaller than the size of any other cut. The illustration on the right shows a maximum cut: the size of the cut is equal to 5, and there is no cut of size 6, or E (the number of edges), because the graph is not See more The family of all cut sets of an undirected graph is known as the cut space of the graph. It forms a vector space over the two-element finite field of arithmetic modulo two, with the symmetric difference of two cut sets as the vector addition operation, and is the See more A cut is minimum if the size or weight of the cut is not larger than the size of any other cut. The illustration on the right shows a minimum … See more The sparsest cut problem is to bipartition the vertices so as to minimize the ratio of the number of edges across the cut divided by the number of vertices in the smaller half of the … See more • Connectivity (graph theory) • Graph cuts in computer vision • Split (graph theory) See more Web本文重点研究了第一类的水平集模型和第二类的 Graph cut 模型在图像分割 中的应用。. （1）我们提出一个新的 Graph cut 模型，该模型利用随机森林算法强 的学习和分类性能，来构建 Graph cut 能量函数，以及相应的图结构。. 然后通过 最大流算法优化我们的模型 ... simple modern art paintings
