Abstract:

In this paper, we propose a new mesh editing method worked in the dual domain for ROI (region of interest). This method has intuitive user interface and efficient reconstruction process. The mesh detail is represented by dual Laplacian, and the reconstructed mesh is obtained by solving a quadratic minimization problem which preserves the mesh detail in least square sense. Preconditioned bi-conjugate gradient method (PBCG) is adopted to iteratively update the positions of the dual vertices and the dual Laplacian coordinates. The experiments demonstrate that our method can work effectively and give visually pleasing results. © 2007 IEEE.
