Finding the surface of a volumetric 3D object is a fundamental problem in computer vision. Energy minimizing splines, such as active surfaces, have been used to carry out such tasks, evolving under the influence of internal and external energies until the model converges to a desired surface. The present deformable model based surface extraction techniques are computationally expensive and are generally...
Active contour methods can be used to segment a 3D mesh into parts by iteratively moving the contour to the mesh region that minimizes the contour energy. However, as the contour moves, it often does not lie on the mesh surface. To address this problem, existing methods use either vertex/edge projection or mesh parameterization to obtain the corresponding contour on the mesh surface. Although vertex/edge...
