We use here the 30 edge detector =-=[7]-=- obtained by generalization of the 2D Canny-Deriche filter. We give in comparison examples of what happens when we do not normalize the image force (Fig. 5). If the time step is too large, the force ~... |

We made a first approach to 3D reconstruction by extracting the contour slice by slice (as in =-=[9]-=- where the curves were extracted by hand, on each slice, using an image of edges). Figures 12 and 13 show the reconstruction of the left and right ventricles. This reconstruction is almost automatic. ... |

Thus, we obtain a linear system and we have to solve a pentadiagonal banded symmetric positive system. We compute the solution using a LU decomposition of (Zd + ... |
