Multi-part models, CSG, superquadrics, 3D image, matching, initial shape.
The application of deformable models in tracking and
segmentation tasks has increased in popularity in the
latest years. These processes can be slow when the user
has to define the initial shape. Moreover, the goodness
of this initial shape has a great influence in the final
result. However, the automatic generation of the initial
model is barely addressed in the literature. We propose
an automatic initialization method that makes a
preliminary estimation of structural properties of
objects in 3D images. This approach takes advantage of
the robustness brought by multi-part parametric models,
a priori shape information and matching techniques.
