not only give the more suitable silhouette but gives in
a classiﬁed way the Nth most probable silhouettes. In
order to evaluate the given result, we used the simula-
tion. By knowing the real skeleton of the test image,
we can process the reprojection error of the estimated
3D joints. According to experimental result, when the
mean error is less than 5 pixels, the pose of the re-
sult is considered similar to the pose of the request
silhouette. For this empiric threshold, the difference
between two silhouettes is hardly visible for a human.
