We present a novel learning-based approach for computing correspondences between non-rigid 3D shapes. Unlike previous methods that either require extensive training data or operate on handcrafted input descriptors and thus generalize poorly across diverse datasets, our approach is both accurate and robust to changes in shape structure. Key to our method is a feature-extraction network that learns directly from raw shape geometry, combined with a novel regularized map extraction layer and loss, based on the functional map representation. We demonstrate through extensive experiments in challenging shape matching scenarios that our method can learn from less training data than existing supervised approaches and generalizes significantly better than current descriptor-based learning methods.

提出了一种基于学习的方法，用于计算非刚性三维形状之间的对应关系。该方法利用从原始形状几何中直接学习的特征提取网络，结合一种基于功能映射表示的正则化地图提取层和损失函数，能够从比现有的监督方法少的训练数据中学习，并且比当前基于描述符学习的方法更加普适。
