We propose an algorithm for non-rigidly registering a 3D template mesh with a dense point cloud, using a morphable shape model to control the deformation of the template mesh. A cost function involving nonrigid shape as well as rigid pose is proposed. Registration is performed by minimizing a first-order approximation of the cost function in the Iterative Closest Points framework. We show how a complex...
A new technique for the reconstruction of a smooth surface from a set of 3D data points is presented. The reconstructed surface is represented by an everywhere C1-continuous subdivision surface which interpolates all the given data points. The new technique consists of two major steps. First, an efficient surface reconstruction method is applied to produce a polyhedral approximation to the given data...
Combined with the fast multiple methods, the boundary element method become quite efficient to deal with large-scale engineering and scientific problems. In this paper, by applying fast multiple expansions, the boundary integral equation about the elastic problem is discrete. In boundary integral equality, because solutions contain singular term 1r , which influences the application of fast multiple...
