The mesh enhancement process. It should be noted that this image depicts the process of upsampling a graph which has N nodes and a feature dimension of d, to a graph with R nodes. The depicted network contains two cascaded levels of graph upsampling followed by the “Coordinate Reconstructor” which calculates the position vector of the upsampled graph. k and q are the feature dimensions that of the generated features at cascaded level 1 and 2. Since the objective of our work is to upsample the graph while retaining the number of features we set \(k = q = d\).
