摘要:

我们提出了一个新的程序来指导训练的数据驱动的形状生成模型使用结构感知损失函数。复杂的3D形状通常可以使用粗略定义的结构来概括,该结构在各种观察中是一致和鲁棒的。然而,现有的合成技术在训练过程中不考虑结构,因此经常生成难以置信的和结构上不现实的形状。在训练过程中,我们强制执行结构约束,以便在整个流形上强制执行一致性和结构。我们提出了一种用于训练3D生成模型的新方法,该方法将结构信息整合到端到端的训练管道中。

英文摘要:

We propose a new procedure to guide training of a data-driven shape generative model using a structure-aware loss function. Complex 3D shapes often can be summarized using a coarsely defined structure which is consistent and robust across variety of observations. However, existing synthesis techniques do not account for structure during training, and thus often generate implausible and structurally unrealistic shapes. During training, we enforce structural constraints in order to enforce consistency and structure across the entire manifold. We propose a novel methodology for training 3D generative models that incorporates structural information into an end-to-end training pipeline.
