rep.matching">Matching score</h2>
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->

<p> The computation of the matching score differs from the repeatability
score. The one-to-one correspondences are not only based on the feature frames
geometry (overlaps) but also the distance in the descriptor space. Therefore
the feature extractor must be able to extract feature descriptors. This is not
the case of MSER feature extractor, so it has to be coupled with a feature
extractor which supports
