• Abstract summary: Shape completion is the problem of inferring the complete geometry of an object given a partial point cloud. This paper proposes the Graph Attention Shape Completion Network (GASCN), a novel neural network model that solves this problem. For each completed point, our model infers the extent of the local surface patch which is used to produce dense yet precise shape completions.

• Abstract: Shape completion, the problem of inferring the complete geometry of an object given a partial point cloud, is an important problem in robotics and computer vision. This paper proposes the Graph Attention Shape Completion Network (GASCN), a novel neural network model that solves this problem. This model combines a graph-based model for encoding local point cloud information with an MLP-based architecture for encoding global information. For each completed point, our model infers the normal and extent of the local surface patch which is used to produce dense yet precise shape completions. We report experiments that demonstrate that GASCN outperforms standard shape completion methods on a standard benchmark drawn from the Shapenet dataset.

This decoupled architecture together with a multi-scale grid feature learning is able to generate more realistic on-surface details.

  Point cloud completion is the task of predicting complete geometry from partial observations using a point set representation for a 3D shape.
