Abstract
This paper proposes a novel approach that allows regionbased active contour energy to be re-expressed combining local and global information. The basic idea of this technique consists in extracting image statistics locally from the heterogeneous region (foreground or background) and globally from the other region at each point along the curve. By exploiting benefits of both local-based and global-based statistics, this technique proves to be robust against heterogeneity and noise and shows low sensitivity to curve initialization. Experimental results for synthetic and real images reveal significant improvement compared to conventional methods.

Résumé
Nous proposons dans ce papier la combinaison des caractéristiques statistiques locales et globales en segmentation par contour actif. L'évaluation de la performance de l'approche proposée sur différents types d'images, présentant des attributs hétérogènes avec une initialisation inadéquate du contour actif ou avec la présence du bruit, a donné des résultats satisfaisants, même quand les méthodes conventionnelles ne parviennent pas à segmenter correctement l'objet d'intérêt.

Abstract
This article presents a new open-source C++ implementation to solve the SLAM problem, which is focused on genericity, versatility and high execution speed. It is based on an original object oriented architecture, that allows the combination of numerous sensors and landmark types, and the integration of various approaches proposed in the literature. The system capacities are illustrated by the presentation of an inertial/vision SLAM approach, for which several improvements over existing methods have been introduced, and that copes with very high dynamic motions. Results with a hand-held camera are presented.
