Abstract
We propose a method for learning non-linear face geometry representations using deep generative models. Our
model is a variational autoencoder with multiple levels of
hidden variables where lower layers capture global geometry and higher ones encode more local deformations. Based
on that, we propose a new parameterization of facial geometry that naturally decomposes the structure of the human
face into a set of semantically meaningful levels of detail.
This parameterization enables us to do model fitting while
capturing varying level of detail under different types of geometrical constraints
