Lossless SAR image compression using integer to integer wavelet transform

The advantages of wavelet transform constructed with lifting scheme are introduced and several integer to integer invertible wavelet transform pairs were given. The features of SAR (synthetic aperture radar) image were described and method for lossless compression of the image by means of integer to integer wavelet transform was presented. This method has the advantages of fast in-place calculation and progressive transfer. Comparing the experimental results for ERS-1 single-look SAR image with IEEE standard images shows that this method is slightly better than DPCM (differential pulse code modulation), and only one decomposition level is needed to compress such image.
