Abstract

The Topological Active Volumes (TAV) model (Barreira and Penedo, 2005) is a general active model focused on 3D segmentation tasks. It can also be used for the surface reconstruction and the topological analysis of the inner side of the detected objects. As any other deformable model, it defines a mesh and several energy functions. The minimisation of the energy functions moves the mesh towards the objects in the scene. The breaking of connections causes topological changes directed to the achievement of specific adjustments. This way, as well as improving the adjustment, the model is able to find several objects in the image and delimit holes in the structures detected. The TAV model achieves accurate results but the computational cost of the segmentation procedure is high. To reduce it, this paper proposes an optimisation of the model. It consists in performing local energy minimisations after the connection breaking process. This way, the execution times are reduced and the accuracy of the results is increased.
