Model Card for OpenLRM V1.1

Overview

  • This model card is for the OpenLRM project, which is an open-source implementation of the paper LRM.
  • Information contained in this model card corresponds to Version 1.1.

Notable Differences from the Original Paper

  • We do not use the deferred back-propagation technique in the original paper.
  • We used random background colors during training.
  • The image encoder is based on the DINOv2 model with register tokens.
  • The triplane decoder contains 4 layers in our implementation.
