Received 17 March 2014 The development is carried out to construct a spatial transformation based on cubic B- Received in revised form 14 December 2014 spline basis functions and determine the control points dynamically. Unlike FEM-based Accepted 8 February 2015 image registration methods, we do not have the difficulty of solving a complicated matrix Available online 24 March 2015 system. In addition, the presented method is enhanced by a multilevel technique, which makes it more efficient and flexible. The numerical results and several comparison studies Keywords: on real bio-medical images show our technique is stable, accurate and fast, especially for Image registration Dynamical multilevel modeling large deformation registration problems.
