逐次非凸凹过程学习图匹配

GNCCP Learning Graph Matching

  • 摘要: 针对传统学习图匹配在抗形变和抗噪声方面性能不够稳定的问题,提出一种有监督的逐次非凸凹过程学习图匹配方法.首先通过逐次非凸凹过程(GNCCP)求解一系列二次分配问题以估计训练目标函数的上界,并采用Bundle方法对上界进行优化,完成图匹配模型的训练;其次,使用GNCCP对图匹配模型进行求解,获得匹配结果.在CMU的House/Hotel数据集以及3个具有旋转、切变和加噪的人工合成数据集上的实验结果表明,文中方法可以大幅提升匹配精度,甚至达到零错误率;在WILLOW数据集上,结合形状上下文边特征描述,也得到了令人满意的效果.

     

    Abstract: Traditional learning graph matching usually performs unstably in case of deformation and noise. For these problems, this paper presents a supervised learning graph matching method combined with graduated non-convexity and concavity procedure(i.e. GNCCP). The method first solves a set of quadratic assignment problems by GNCCP to get the convex upper bound of the training problem, which is subsequently optimized by the bundle method; after that, we use GNCCP again for the trained graph matching model to get the final matching. On CMU House/Hotel data sets and three synthetic data sets with rotation, shear and noise, experimental results show that the method can significantly improve the matching accuracies and even up to 100% for some data sets. In addition, with a shape context pairwise feature descriptor the proposed method can perform competitively on the WILLOW data set.
