sketchShape

This code implements the tasks for sketch-based 3D shape trieval

Method

The methods are divided into sevaral steps:

• Multiview renderding. The shape are rendered on 12 different views.
• 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.
