Size-Dependent Segmentation of Extrusions and Hollows in Triangular Meshes With the Level Set Method

The level set method (LSM) is used in a wide variety of applications. In this paper, the authors propose an approach to detect and eliminate protruding and hollow features in triangular meshes using the technique. First, uniform grid points are generated based on a given mesh model, and these points are then clustered with respect to a user-defined threshold using LSM. Finally, the mesh model is segmented in consideration of the grouped grid points. The results of experiments performed using the proposed method indicate its suitability for the purpose at hand.
