Query: EmoGen: Quantifiable Emotion Generation and Analysis for Experimental
  Psychology   3D facial modelling and animation in computer vision and graphics
traditionally require either digital artist's skill or complex pipelines with
objective-function-based solvers to fit models to motion capture. This
inaccessibility of quality modelling to a non-expert is an impediment to
effective quantitative study of facial stimuli in experimental psychology. The
EmoGen methodology we present in this paper solves the issue democratising
facial modelling technology. EmoGen is a robust and configurable framework
letting anyone author arbitrary quantifiable facial expressions in 3D through a
user-guided genetic algorithm search. Beyond sample generation, our methodology
is made complete with techniques to analyse distributions of these expressions
in a principled way. This paper covers the technical aspects of expression
generation, specifically our production-quality facial blendshape model,
automatic corrective mechanisms of implausible facial configurations in the
absence of artist's supervision and the genetic algorithm implementation
employed in the model space search. Further, we provide a comparative
evaluation of ways to quantify generated facial expressions in the blendshape
and geometric domains and compare them theoretically and empirically. The
purpose of this analysis is 1. to define a similarity cost function to simulate
model space search for convergence and parameter dependence assessment of the
genetic algorithm and 2. to inform the best practices in the data distribution
analysis for experimental psychology.
