Aiming at the limitation of Expectation Maximization(EM) algorithm for mixture model parameters,this paper presents a fuzzy constrained mixture model for image segmentation.According to the mixture model based on the precondition of pixel independence,it solves the parameters of model by Expectation Maximization(EM) algorithm.The pixel spatial information with the fuzzy method is introduced to correct the independent assumption of the pixel and reduces the influence among the parameters of mixture components.Experimental results show the al...
