In this algorithm, the probability density functions of the differente images are estimated as Gaussian mixture distributions. A fast estimation procedure for the posterior marginals is added to the MAP algorithm.Firstly,initial segmentation is applied to obtain number of the initial motions and the corresponding initial parameters of the motion model.Then the parameters are updated by using the given parameter estimation method. The experiment results show that the proposed algorithm here is effective. %U http://cea.ceaj.org/EN/abstract/article_18617.shtml
