| Abstract: | Dissimilarity measures are often used to describe the difference between the polarimetric SAR(PolSAR) samples,which have been widely used in various PolSAR image interpretation techniques,such as filtering,object detection,segmentation,classification and change detection.Based on matrix expression form for PolSAR data,the dissimilarity measures in PolSAR image interpretation is summarized and reviewed from such aspects as feature,statistical distribution,hypothesis test,information theory divergence,information geometry and so on.The advantages,problems and applications of these dissimilarity measures are briefly analyzed.Finally,The future study of PolSAR dissimilarity measures is pointed out. |
