In order to realize the fast precise image registration,a mutual information image registration method based on improved particle swarm optimization is proposed.Mutual information is used as the similar measure.The improved particle swarm optimization algorithm solves the space transformation parameters of registration.The organization concept is introduced in the methtod to divide the entire population into several sub-groups,meanwhile the mutation operation in genetic algorithm is introduced to reduce the local extreme.And improved PSO is used in the medical image registration.The results show that the method can achieve more satisfied results of the image registration.
