Lossless SAR Image Compression Using Integer to Integer Wavelet Transform

  • Received Date: 24 Nov 1998

  • Three advantages of wavelet transform constructed with lifting scheme are introduced and then invertible wavelet transform pairs of several integer to integer have been given. After discussed the features of SAR image, a method for lossless compression of SAR image by means of integer to integer wavelet transform has been presented. The advantages of the method are fast in-place calculation and progressive transfer. The experimental results for ERS-1 single-look SAR images and IEEE standard images show that the method is slightly better than DPCM, and only one decomposition level is needed to compress SAR image and more levels are not necessary.
