The study of human anatomy presents the most difficult challenges to the understudy of typicality and variablity. While Biological shapes are highly structured, they are not rigid. Dr. Miller has been using Grenander's deformable anatomical templates for the representation of the typicality and for the representation of the variablilty. For this, complex anatomical templates (human and macaque brains) are annotated with coordinate systems defined within them. High-dimensional vector fields applied to these coordinate systems carry the templates with all of its geometry into the target. This allows for understanding modulo individual variation.
