N2 - Continuous shape change is represented as curves in the shape space. A method
for checking the closeness of these curves to a geodesic is presented. Three large
databases of short human motions are considered and shown to be well-approximated
by geodesics. The motions are thus approximated by two shapes on the geodesic and the
rate of progress along the path. An analysis of facial motion data taken from a study
of subjects with cleft lip/palate is presented that allows the motion to be considered independently
from the static shape. Inferential methods for assessing the change in motion are presented. The construction of predicted animated motions is discussed.
