In this thesis, we are interested in using deformable surface models for 3D and 4D image segmentation. Our contribution is twofold. First, we have constrained the...

The segmentation of abdomen organs in volumetric medical images is difficult due to noisy and low contrasted images. Classical segmentation technics based on edge...

Several methods based on the use of Voronoi diagrams, are proposed for the 3D and 2D reconstruction of natural objects. The main application domain is geology. A first...

Deformable models or active contours are used for edge detection in image analysis and picture processing.<br />We purpose in this thesis, to study these models...
