Code release for "Multi-view Supervision for Single-view Reconstruction via Differentiable Ray Consistency" (CVPR 2017)

Multi-view Supervision for Single-view Reconstruction via Differentiable Ray Consistency

Shubham Tulsiani, Tinghui Zhou, Alexei A. Efros, Jitendra Malik. In CVPR, 2017. Project Page

Demo and Pre-trained Models

Please check out the interactive notebook which shows reconstructions using the learned models. You'll need to -

• Install a working implementation of torch and itorch.
• Download the pre-trained models for Pascal3D (490MB) and ShapeNet (250MB). Extract the pretrained models to 'cachedir/snapshots/{pascal,shapenet}/'
• Edit the path to the blender executable in the demo script.

Loss Function Compilation

To use our proposed loss function for training, we need to compile the C implementation so it can be used in Torch.

cd drcLoss
luarocks make rpsem-alpha-1.rockspec

Training and Evaluating

For training your own models and evaluating those, or for reproducing the main experiments in the paper, please see the detailed README files for PASCAL3D or ShapeNet.

Additional Dependencies

You'll need to install some additional dependencies (json and matio).

sudo apt-get install libmatio2
luarocks install matio
luarocks install json
