Résumé :
Les champs de Gibbs sont très utilisés en traitement d'image à la fois pour la segmentation et la restauration. Définis sur la trâme discrète sous-jacente à l'image, ils présentent un comportement non isotrope. Dans ce rapport, nous étudions et quantifions cette non-isotropie, pour des modèles avec des interactions 3x3, en calculant la tension de bord en fonction de l'angle d'une droite séparant le plan en deux parties contenant une phase différente. De cette étude, nous dérivons deux critères quantitatifs d'anisotropie des modèles. Nous calculons ensuite la forme d'une goutte d'une phase immergée dans une autre phase à la température nulle pour les différents modèles, et étudions la non isotropie des formes obtenues. Pour finir, les artéfacts induits par cette non-isotropie sont mis en évidence sur des exemples de segmentation et de restauration d'image. |
Abstract :
Gibbs Fields are widely used in image processing for both segmentation and restoration. Defined on a discrete lattice representing the image they exhibit a non-isotropic behavior. Herein, we study and quantify this non-isotropy by computing the boundary tension as a function of the angle of a line separating the plane in two parts containing a different phase. From this study, we derive two quantitative criteria of the non isotropy of the model. We then compute the shape at zero temperature of a droplet of one phase within the other phase and study the non-isotropy of the shape for the different models. Finally, we show the artifacts due to this non-isotropic behavior for image segmentation and restoration. |
