Le cadre de l’appariement d’images via des groupes de difféomorphismes est étendu à l’ensemble des fonctions à variation bornée. Le résultat principal de l’article est la différenciation du terme d’attache aux données de la fonctionnelle à minimiser. On établit ainsi les équations géodésiques associées à ce problème variationnel pour un terme d’attache général et on décrit le moment relatif à cette géodésique.The image matching within the framework of large deformations via diffeomorphisms is extended to the space of bounded variation functions. Thanks to a semi-differentiation lemma, which is the central new result of this article, we derive the geodesic equations for a general penalty term and we describe the associated momentumou
