Before revision:  Our modules use Graph Convolutional Networks (GCNs) to better encode local point information . Our upsampling modules are versatile and can be incorporated into any point cloud upsampling pipeline.
After revision:  Our modules use Graph Convolutional Networks (GCNs) to better encode local point information from the point neighborhood. These upsampling modules are versatile and can be incorporated into any point cloud upsampling pipeline.
