Abstract :
A lossless image compression algorithm using the integer wavelet transform is proposed in this paper. The S+P wavelet transform is compared with the various integer coefficient filter banks (ICFB), and the 9/7 ICFB is applied to the wavelet transform. The compression ratios of the proposed algorithm are compared with those of the S+P transform for several different types of images
