PT Unknown AU Mohammad Rouhani Angel Sappa TI Non-Rigid Shape Registration: A Single Linear Least Squares Framework BT 12th European Conference on Computer Vision PY 2012 BP 264 EP 277 VL 7578 DI 10.1007/978-3-642-33786-4_20 AB This paper proposes a non-rigid registration formulation capturing both global and local deformations in a single framework. This formulation is based on a quadratic estimation of the registration distance 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. ER
