Primal-Dual Mesh Convolutional Neural Networks

Authors: Francesco Milano, Antonio Loquercio, Antoni Rosinol, Davide Scaramuzza, Luca Carlone

Installation

Please follow the instructions in the file install.md.

Training and evaluation

  • For a detailed explanation on how to run a training job and perform evaluation on the test set, please see training.md and evaluation.md, respectively.
  • To reproduce the paper results, either by retraining a network or by using a pretrained model, please see results.md.

Datasets

The code provided automatically downloads the datasets SHREC and Cube Engraving in the downsampled version provided by MeshCNN. For the SHREC dataset, we randomly generated two new sets for Split 16 and three sets for Split 10 (cf. main paper). We also automatically download the COSEG and Human Body datasets, which we preprocessed from the version provided by MeshCNN so as to convert ground-truth labels on the edges to ground-truth labels on the faces (cf., e.g., pd_mesh_net.datasets.coseg_dual_primal.py).

Unit tests

For details on how to run unit tests, please see unit_tests.md.
