SAR Image Speckle Reduction Algorithm Based on Linear plan

摘要：

A new best threshold algorithm is presented for speckle reduction in this paper. It ensures the most accurate threshold on different decomposing layers. Combining classical linear plan methods, this thresholdsearching problem can become an abstracted linear plan problem if wavelet coefficients and amount of decomposing layer have been known before. A graphic solution could be used to calculate the best threshold on different decomposing layers. The experimental results show that the new algorithm can have a good effect on speckle reduction, and it can reserve details of the SAR images.
