The methods are divided into sevaral steps:

  • Multiview renderding. The shape are rendered on 12 different views. multiview rendering
  • Finetune. The sketches and rendered shape images are finetuned with AlexNet as single image classification task. The finetuned features for both shrec13 and shrec14 could be downloaded as follows: 
    chmod +x download.sh
./download.sh
  • The shape features passed through a linear combination to form one global representation. Contrastive loss are employed for both within-domain pair and across-domain pair.
