要旨:
Flexible models of object classes, based on linear combinations of
prototypical images, are capable of matching novel images of the same class
and have been shown to be a powerful tool to solve several fundamental vision
tasks such as recognition, synthesis and correspondence. The key problem in
creating a specific flexible model is the computation of pixelwise
correspondence between the prototypes, a task done until now in a
semiautomatic way. In this paper we describe an algorithm that automatically
bootstraps the correspondence between the prototypes. The algorithm - which
can be used for 2D images as well as for 3D models - is shown to synthesize
successfully a flexible model of frontal face images and a flexible model of
handwritten digits.
