Thanks for sharing this projetct! Does the 256-dimensional expression vector have any specific meaning? Similar to iPhone arkit52, https://arkit-face-blendshapes.com/.

Hi! thanks for your question. Unfortunately the expression vector was implicitly learned, so there isnt an explicit representation or interpretation for each dimension. But in case this is helpful, here are a few links to learn more about the process:

• "Deep Appearance Models for Face Rendering" (https://arxiv.org/abs/1808.00362)
• code + data: https://github.com/facebookresearch/multiface
