中文简介:
我们考虑在两组特征之间找到匹配的问题,给出它们之间的复杂关系,超越成对。我们在由凸优化表示的概率设置中导出超图匹配问题。首先,我们将问题输入和输出的概率解释中出现的软匹配标准形式化,而不是先前将软匹配视为仅仅放松硬匹配问题的方法。其次,该模型引起超边缘权重矩阵与期望顶点到顶点概率匹配之间的代数关系。第三,该模型解释了过去在启发式基础上提出的一些图匹配归一化,例如边权重的双重随机归一化。该模型的主要优点是可以通过迭代连续投影算法找到匹配标准的全局最优。当两个图具有相同数量的顶点并且需要完全匹配时,该算法在特殊情况下简化为众所周知的Sinkhorn行/列矩阵归一化过程。我们模型的另一个好处是从图形到超图形的直接可扩展性。这项工作是由Ron Zass完成的(并于2008年CVPR首次亮相)
课程简介: We consider the problem of finding a matching between two sets of features, given complex relations among them, going beyond pairwise. We derive the hyper-graph matching problem in a probabilistic setting represented by a convex optimization. First, we formalize a soft matching criterion that emerges from a probabilistic interpretation of the problem input and output, as opposed to previous methods that treat soft matching as a mere relaxation of the hard matching problem. Second, the model induces an algebraic relation between the hyper-edge weight matrix and the desired vertex-to-vertex probabilistic matching. Third, the model explains some of the graph matching normalization proposed in the past on a heuristic basis such as doubly stochastic normalizations of the edge weights. A key benefit of the model is that the global optimum of the matching criteria can be found via an iterative successive projection algorithm. The algorithm reduces to the well known Sinkhorn row/column matrix normalization procedure in the special case when the two graphs have the same number of vertices and a complete matching is desired. Another benefit of our model is the straightforward scalability from graphs to hyper-graphs. The work was done with Ron Zass (and made its debut in CVPR 2008)
