| Abstract: | A new adapted speckle filtering algorithm is presented on the speckle noise statistics in thispaper,which is able to reduce the speckle noise and selete filtering window for SAR images .The algorithm is presented for application to SeasatAR images.The experimental rcsults are comparised with that ofLee and Oddy s,which operates along similar computational principles.The quantitative comparison resultsassess that our algorithm may be a more robust one. |
