The point cloud is the basis for 3D object surface reconstruction. An incomplete significantly reduces accuracy of downstream work such as reconstruction and recognition. Therefore, point-cloud repair indispensable work. However, original shape difficult to restore due uncertainty position new filling point. Considering advantages convex set in dealing with problems, we propose a method via tha...

We introduce Coherent Point Drift (CPD), a novel probabilistic method for nonrigid registration of point sets. The registration is treated as a Maximum Likelihood (ML) estimation problem with motion coherence constraint over the velocity field such that one point set moves coherently to align with the second set. We formulate the motion coherence constraint and derive a solution of regularized ...

the aim of this work is to describe the qualitative behavior of the solution set of a givensystem of fractional differential equations and limiting behavior of the dynamical system or flow defined by the system of fractional differential equations. in order to achieve this goal, it is first necessary to develop the local theory for fractional nonlinear systems. this is done by the extension of ...
