The speckle filtering in polarimetric SAR images is very important to its post-processing.For that the independent component analysis(ICA)is unstable and easily falls into the local optimum,an improved independent component analysis based on particle swarm optimization(PSO)algorithm was proposed in this paper to reduce the polarimetric SAR image speckle.The algorithm focused on improving the generation process of the un-mixing matrix W by PSO algorithm,and improving the separation efficiency of the original...
