论文摘要
由于3D格式存储的大量信息,3D深度学习是一个越来越多的感兴趣领域。三角形网格是不规则,不均匀3D对象的有效表示。但是,由于其高几何复杂性,网格通常具有挑战性的注释。具体而言,为网格创建细分面罩是繁琐的时必时间。因此,希望使用有限标记的数据训练分割网络。自我监督的学习(SSL)是一种无监督的表示学习的一种形式,它是对完全监督学习的替代方法,可以减轻培训的监督负担。我们提出了SSL-MESHCNN,这是一种用于网格分割的预训练CNN的自我监督的对比学习方法。我们从传统的对比学习框架中汲取灵感来设计专门针对网格的新颖对比度学习算法。我们的初步实验显示了将网状分割所需的重型标记数据需求减少至少33%的有希望的结果。
3D deep learning is a growing field of interest due to the vast amount of information stored in 3D formats. Triangular meshes are an efficient representation for irregular, non-uniform 3D objects. However, meshes are often challenging to annotate due to their high geometrical complexity. Specifically, creating segmentation masks for meshes is tedious and time-consuming. Therefore, it is desirable to train segmentation networks with limited-labeled data. Self-supervised learning (SSL), a form of unsupervised representation learning, is a growing alternative to fully-supervised learning which can decrease the burden of supervision for training. We propose SSL-MeshCNN, a self-supervised contrastive learning method for pre-training CNNs for mesh segmentation. We take inspiration from traditional contrastive learning frameworks to design a novel contrastive learning algorithm specifically for meshes. Our preliminary experiments show promising results in reducing the heavy labeled data requirement needed for mesh segmentation by at least 33%.
