A novel method for solving the automated registration problems based on the global optical flow field and feature extracted from images is proposed. The method can be preformed with three steps. Firstly, the global optical flow field is computed, which provides a platform of background registration. Secondly, the optical flow field and the edge feature of moving target are integrated to segment the whole target. Finally, the registration of moving targets is finished through the transformation computation of perspective projection model. The simulation experiments for infrared images show that the method proposed is not accurate, but robust to motion of scene, which is ideally suited for the application of automated image registration.
