具有交互边代价的图切割-示例、近似和算法

Graph Cuts with Interacting Edge Costs - Examples, Approximations, and Algorithms

Stefanie Jegelka, Jeff Bilmes

摘要:

我们研究了经典的图切割问题的扩展,其中我们取代了模块化(边缘权重的总和)的成本函数由一个子模块化的集函数定义在图的边缘。在信号处理、机器学习和计算机视觉的不同应用中出现了这个问题的特殊情况。在本文中,我们通过“合作图切割”的通用配方连接这些应用程序,我们研究的复杂性,算法和连接到polymatroidal网络流。最后,我们比较所提出的算法经验。

英文摘要:

We study an extension of the classical graph cut problem, wherein we replace the modular (sum of edge weights) cost function by a submodular set function defined over graph edges. Special cases of this problem have appeared in different applications in signal processing, machine learning, and computer vision. In this paper, we connect these applications via the generic formulation of "cooperative graph cuts", for which we study complexity, algorithms, and connections to polymatroidal network flows. Finally, we compare the proposed algorithms empirically.
