Query: Classification of geometrical objects by integrating currents and
  functional data analysis. An application to a 3D database of Spanish child
  population   This paper focuses on the application of Discriminant Analysis to a set of
geometrical objects (bodies) characterized by currents. A current is a relevant
mathematical object to model geometrical data, like hypersurfaces, through
integration of vector fields along them. As a consequence of the choice of a
vector-valued Reproducing Kernel Hilbert Space (RKHS) as a test space to
integrate hypersurfaces, it is possible to consider that hypersurfaces are
embedded in this Hilbert space. This embedding enables us to consider
classification algorithms of geometrical objects. A method to apply Functional
Discriminant Analysis in the obtained vector-valued RKHS is given. This method
is based on the eigenfunction decomposition of the kernel. So, the novelty of
this paper is the reformulation of a size and shape classification problem in
Functional Data Analysis terms using the theory of currents and vector-valued
RKHS. This approach is applied to a 3D database obtained from an anthropometric
survey of the Spanish child population with a potential application to online
sales of children's wear.
