Face-space: linking three-dimensional shape and human perception across changing viewing conditions.

Abstract

  • Three-dimensional face databases are increasingly used in numerous fields including crime prevention. We will relate these physical measurements to human perception. Using established methods, we will define both physical and psychological face spaces that capture the actual and perceived differences between people. We will then compare and combine physical and psychological spaces through the shared metric of similarity. How the mapping is limited by viewing conditions will be a focus of research. The result will be a physically defined, psychologically valid hybrid face space predictive of human perception. We will then define objective threshold differences that correspond to a perceived change in identity within that space.
