Interactive Segmentation of 3D Images Using a Region Adjacency Graph Representation
Résumé
This paper presents an interactive method for 3D images segmentation. This method is based on a region adjacency graph representation that improves and simplifies the segmentation process. This graph representation allows the user to easily define some splitting and merging operations which gives the possibility to make an incremental construction of the final segmentation. To validate the interest of the proposed method, our interactive proposition has been integrated into a volumetric texture segmentation process. The obtained results are very satisfactory even in the case of complex volumetric textures. This same system, including the textural features and our interactive proposition, has been manipulated by specialists in sonography to segment 3D ultrasound images of the skin. Some examples of segmentation are presented to illustrate the interactivity of our approach.
