Powell方向集方法（PDSM）是一种广泛应用于图像配准的方法。然而，它的性能被发现是强烈依赖于初始解。在本文中，我们提出了一种新的组合PDSM与初始化的差分进化遗传算法。为了进一步提高收敛性，采用了多分辨率方法。互信息被选为本次调查的误差度量。实验结果表明，该方法有效地提高了PDSM的性能，具有较强的鲁棒性。
Powell's direction set method (PDSM) is widely used in image registration. However, its performance is found to be strongly dependent on the initial solution. In this paper we propose a novel combination of PDSM with initialization by the differential evolution genetic algorithm. To further improve the convergence, a multi-resolution approach is taken. Mutual information is chosen as the error metric for this investigation. The results presented show that this proposed method does significantly improve the performance of PDSM and it is efficient and robust.
