173 Wavelet-based Technology of Reduced Coherent Speckle for SAR Image
LI Wan-she, Zheng Bao · Journal of the Visualization Society of Japan · 2000
This paper studies Synthetic Aperture Radar (SAR) images with the wavelets transform of lifting scheme, presents a new denoising method of wavelets analytic to reduce the coherent speckle noise. A lot of experiments approve that this new method not only suppresses the speckle noise effectively, but also preserves as many target characteristics of original images as possible. It shows that this denoising method offers a very attractive alternative to suppress the coherent speckle noise of the SAR images.
