Abstract

Techniques devoted to generate triangular or tetrahedral meshes from images either take as starting point a pre-processed image or generate a mesh without distinguishing different structures contained in the image. The pre-process and the absence of well defined structures may impose difficulties in using the resulting mesh in some applications as, for example, numerical simulations. In this work, we present a new technique that aims at eliminating the need for pre-processing by building the segmentation into the mesh generation process. Furthermore, the proposed technique consider quality criteria in the generated meshes, being appropriated for applications in numerical simulation as well as in image modeling (AU)
