Representing multifigure anatomical objects

We use multifigure m-reps to represent anatomical objects, such as human livers, with named components. Each component is represented as a single figure m-rep. These figures of the object are connected via hinge geometry. A smooth object surface is then computed using our technique based on the subdivision method applied to a single figure m-rep. This novel representation allows us to represent and analyze a complex anatomical object by its individual components, by relations among its components, and by the object itself as a whole entity. Using our representation, some preliminary results on statistical analysis of multifigure anatomical objects are presented.
