Training models of shape from sets of examples

Research output: Chapter in Book/Report/Conference proceedingConference contribution


A method for building flexible shape models is presented in which a shape is
represented by a set of labelled points. The technique determines the statistics
of the points over a collection of example shapes. The mean positions of the
points give an average shape and a number of modes of variation are determined
describing the main ways in which the example shapes tend to deform
from the average. In this way allowed variation in shape can be included in the
model. The method produces a compact flexible 'Point Distribution Model'
with a small number of linearly independent parameters, which can be used
during image search. We demonstrate the application of the Point Distribution
Model in describing two classes of shapes.
