Résumé | Liens | BibTeX | Étiquettes: Estimation;Channel estimation;Geoscience and remote sensing;Mean square error methods;Speckle;Information filters;Distortion;Speckle;MMSE filter;PolSAR;span @inproceedings{9554095, The use of the span as a reference image in PolSAR speckle filtering is investigated. It has been demonstrated in this study that span reduced the speckle noise in extended homogeneous areas differently, degraded the spatial details and distorted the filtered intensity image. Then, the impact of span on the filtered PolSAR images is evaluated. The results showed that the drawbacks of the span filtering in terms of speckle filtering, spatial detail and polarimetric information preservation are propagated to the minimum mean square error MMSE-based PolSAR filters. The estimation of the filtering weights from the intensity channels rather than the span resolved these issues. |
