An Effective SAR Image Denoising Method
Yongmei Zhang, Ming Feng Jiang · International Conference on Electronics, Communications and Control · 2012
The existing speckle noise in SAR image produces serious impact on the feature extraction or other processing. Filter is needed to reduce and overcome the adverse effects of speckle noise. This paper presents a algorithm of multi-level non-linear weighted mean median filtering, smoothly filtering SAR, effectively suppressing speckle noise in images while maintaining the image geometry, and objectively evaluate denoising effects. Experiment results show that the algorithm is effective to preserve the useful information of the images, so as to eliminate or reduce the impact of noise on the subsequent processing.
