SAR image compression is very important in reducing the costs of data storage and transmission in relatively slow channels. In this paper, we propose a compression scheme driven by texture analysis, image segmentation and speckle noise reduction within the wavelet framework. The result is favourable compared to the conventional zero-tree wavelet compression method
