The current ebook comprises prolonged types of papers offered within the overseas convention VIPIMAGE 2007 – ECCOMAS Thematic convention on Computational imaginative and prescient and clinical picture, held in Faculdade de Engenharia da Universidade do Porto, in 17-19 of October 2007. This convention used to be the 1st ECCOMAS thematic convention on computational imaginative and prescient and clinical snapshot processing. It covers issues comparable with photo processing and research, scientific imaging and computational modeling and simulation, contemplating their multidisciplinary. This e-book collects the state of the art learn, equipment and new rules with reference to computational imaginative and prescient and clinical picture processing contributing for the advance of those parts of data.

We have developed two algorithms for such purposes – TetMesh and HexMesh. The approach is as follows. First we extract a correct boundary using the boundary element meshing. For tetrahedral mesh generation we use the triangulated boundary and for hexahedral mesh generation we use the quadrangulated boundary meshing scheme as described above. Next, we design a series of templates to build a solid tetrahedral or hexahedral mesh from that conforms with the boundary mesh. The details about the templates are given in [138, 154].

Until recently there were very works that dealt with the problem of building a control quadrilateral mesh from a free-form geometry of arbitrary topology [145, 146]. Recently there have been substantial research works in the computer graphics community that tackled the problem of quadrangulating a surface mesh following the intrinsic anisotropy of the geometry [147–149]. Following these approaches, one can build a quadrilateral base surface mesh on which any of the standard subdivision scheme can be applied to build the desired B-Spline model.
