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.
