Data-driven PolSAR Unsupervised Classification Based on Adaptive Model-based Decomposition
In this paper,we propose a data-driven unsupervised PoiSAR image classification algorithm using adaptive model-based decomposition.By estimating a mean orientation angle and a degree of randomness for canopy scattering,the adaptive decomposition method provides a refined expression of volume scattering component in which no scattering reflection assumption is required.The classification algorithm combines affinity propagation and iterated Wishart classifier.In terms of being data-driven,it can automatically determine the number of clusters.Experimental results on the NASA/JPL AIRSAR L-band PolSAR data of San Francisco demonstrate the effectiveness of our algorithm.
