Improved Medical Image Registration Algorithm Based on Maximization of Normalized Mutual Information
Bei Wang · Journal of Guizhou University · 2008
In this paper a medical image registration algorithm based on maximization of normalized mutual information was proposed.The algorithm uses the improved partial volume distribution interpolation,effectively overcome the local extremum problem which in common image registration.The algorithm uses the maximization mutual information as the objective function and uses the POWELL algorithm search one maximization mutual information to get the best registration parameters.Experiment results show that the proposed algorithm is simple,fast,and can achieve better accuracy and robustness.
