Non-rigid Shape Registration: A Single Linear Least Squares Framework*

Abstract

This paper proposes a non-rigid registration formulation cap- turing both global and local deformations in a single framework. This formulation is based on a quadratic estimation of the registration dis- tance together with a quadratic regularization term. Hence, the optimal transformation parameters are easily obtained by solving a liner system of equations, which guarantee a fast convergence. Experimental results with challenging 2D and 3D shapes are presented to show the validity of the proposed framework. Furthermore, comparisons with the most relevant approaches are provided.
