The whole mesh Deformation Model for 2D and 3D image segmentation [PDF]
In this paper we present a novel approach for image segmentation using Active Nets and Active Volumes. Those solutions are based on the Deformable Models, with slight difference in the method for describing the shapes of interests - instead of using a ...

Progressive deforming meshes based on deformation oriented decimation [PDF]
Progressive Meshes (PM) presented by Hoppe [1996] is a method for representing a static 3D model with continuous levels-of-details (LODs) based on iterative edge-collapse/vertex-split operations. Besides static models, animation models or so-called deforming meshes are more widely used recently.

Nonlinear dynamics analysis of a gear system considering tooth contact temperature and dynamic wear
Increased temperature and surface wear of high-speed and heavy-load gears are inevitable. Thermal deformation and surface wear modify the position of the action line of the tooth surface and thus influence the dynamic characteristics of the gear mesh. In
