Abstract. The aim of this paper is to propose efficient tools for analysing
shape families using morphological operators. The developments include
the definition of shape statistics (mean and variance of shapes, modes of
shape variation) and the interpolation/extrapolation in shape geodesic
paths. The main required ingredients for the operators and the algorithms
here introduced are well known in mathematical morphology such as the
median set, the watershed on distance functions or the interpolation func-
tion. In addition, the projection of shapes in spaces with reduced dimen-
sions using PCA or ISOMAP techniques permits to apply morphological
interpolation techniques in shape manifolds.

where Xi P(E) represents the set (or binary image) of the shape i, and the
