Template-Based Remeshing for Image Decomposition

This paper presents a novel quad-based remeshing scheme, which can be regarded as a replacement for the triangle-based improvement step of an existing image-based mesh generation technique called Imesh. This remeshing scheme makes it possible for the algorithm to generate good quality quadrilateral meshes directly from imaging data. The extended algorithm combines two ingredients: (1) a template-based triangulation-to-quadrangulation conversion strategy and (2) an optimization-based smoothing procedure. Examples of meshes generated by the extended algorithm, and an evaluation of the quality of those meshes are presented as well.
