HDM Demo: Upload your own human object interaction image and get full 3D reconstruction!

Official Demo of "Template Free Reconstruction of Human Object Interaction with Procedural Generation", CVPR'24.

Project Page | Code | ProciGen Dataset | Paper

Instruction:

  1. Upload an RGB image of human object interaction.
  2. Upload the mask for the human and object that you want to reconstruct. You can use these methods to obtain the masks: SAM, SAM-HQ, FastSAM.
  3. Click `Start Reconstruction` to start.
  4. You can view the result at `Reconstructed point cloud` and download the point cloud at `download results`.
Alternatively, you can click one of the examples below and start reconstruction.

More example results can be found in our Project Page.

Have fun!
