Recently, Synthetic Aperture Radar (SAR) has been widely applied in ocean remote sensing, since its charming advantages. However, the subsequent understanding of SAR images is difficult because of the existence of speckles. Traditional denoising methods fail to remove speckles while preserving edges. Local anisotropy degree derived from nonlinear structure tensor was introduced to distinguish structures...
The aliasing of the speckle noise and echo information of sea SAR blurs the structure character of sea SAR image. It is difficult that to enhance structure character of sea SAR image. Aiming at this difficulty, we propose a amalgamation frame based on EMD and exponent. The frame can effectively filter the speckle noise and enhance the structure character which finally can be seen by peoplepsilas eyes...
