One SAR image filtering method based on the heterogeneity measurement
Shaobo Chen, Tao Zhang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2011
The deviation coefficient (Cv) and the arithmetic-geometric mean ratio (A/G) are two kinds of different measurement methods of SAR image heterogeneity. They are widely used for SAR image processing. This paper analyzes the Kuan filtering algorithm based on the deviation coefficient and puts forward the Kuan filtering algorithm based on the arithmetic-geometric mean ratio. And meanwhile, it analyzes and compares the two types of adaptive speckle noise filters through the experiment.
