This research investigates the
problem of recovering information about the configuration of an
articulated object, such as a human figure,
from point correspondences in a single image. Unlike previous
approaches, the proposed reconstruction method does not assume
that the imagery was acquired with a calibrated camera. An analysis
is presented which demonstrates that there are a family of solutions
to
this reconstruction problem parameterized by a single variable.
A simple and effective algorithm is proposed for recovering the
entire
set of solutions by considering the foreshortening of the segments
of the model in the image. Results obtained by applying this
algorithm to real images are presented below.
