Change detection algorithm of remote sensing images based on GA-EM for GMM
基于GA-EM算法的GMM遥感影像变化检测方法*

This paper presentd a change detection algorithm of remote sensing images based on GA-EM for GMM.This method constructed difference image by using PCA and subtraction operation,then modeled the difference image distribution by using N components GMM,again,used an evolutionary iterative adaptive method to estimate the parameters of model,finally,achieved the change detection result of the distributions of changed and unchanged pixels by Bayesian rules.Simulation results show that the method can effectively d...
