The article discusses the interposition problem in augmented reality-that
is, the realistic and physically-consistent embedding of a 3D virtual
object (3DVO) into a real scene. Our method deals with stereoscopic
views of an unstructured and unknown real scene and avoids explicit
3D reconstruction. Instead, we consider a 3DVO as a set of vertices
and rely on local stereo matching to decide whether each vertex should
be visible or not. We focus on the choice of an optimal matching
criterion in the particular context of interposition in augmented
reality. After a brief presentation of our innovative solution, we
review classical matching spaces and criteria, and select the most
appropriate for our task. We compare and interpret their performance
against parameters such as noise level and matching window size and
present preliminary results of interposition for real scenes
