Abstract In this paper a new algorithm for SAR image lossy compression based on lifting scheme is brought forward, aiming at special characteristics of SAR imagery. The algorithm can reduce the speckle noise, improve the computation precision and time, and upswing the compression ability. The algorithm adopts embedded zerotree wavelets, making good use of the wavelet coefficients .Large numbers of SAR images validate the efficiency of the proposed algorithm.The results compare favorably with that of other image compression methods.
