Özet:

 

Synthetic aperture radar (SAR) has been extensively   adopted in a variety of fields, e.g., agriculture and marine fields. In this   regard, the improvement of SAR image quality has aroused a wide concern   worldwide. In recent years, image processing based on local patches has been   very popular and proven feasible. In this paper, a novel SAR image denoising   algorithm is proposed in the NSST domain on the basis of patch ordering.   First, the shearlet transform is applied to logarithmic transformation of   the noisy SAR image. Second, the coefficients of the shearlet are denoised   respectively by combining patch ordering and 1D filtering. Finally, the   denoised SAR image can be obtained by exponential transformation after   applying the inverse shearlet to denoised coefficients. The experimental   results show that the proposed method not only effectively suppresses the   speckle noise and improves the PSNR and ENL of denoising the SAR images but   also obviously improves the visual effects of the SAR images, especially in   maintaining the image edge and texture information.
