Abstract :
This paper presents a novel speckle noise suppression and SAR image compression scheme in discret wavelet domain. First, in the novel speckle noise suppression, a modified soft-thresholding denoising method was applied to reduce speckle noise and it can protect more edge information at the meantime. Then, a new SAR image compression structure based on JPEG2000 was presented. The efficiency of the proposed structure is demonstrated.
