Method of SAR image enhancement and denoising based on wavelet analysis
Jingwen Yan · Jisuanji gongcheng yu sheji · 2004
A method of SAR image enhancement and denoising based on wavelet transform is presented. In this method, wavelet transform is applied to the noise polluted SAR image firstly, and then the SAR image is filtered by a smooth filter in the wavelet domain. Finally a SAR image denoising system is implemented. From the result, it can be seen that better result can be attained by this method relative to the method of using smooth filter to process the SAR image directly. And a good base for further image segmentation or recognition is built.
