| Abstract: | Remote sensing image compression based on wavelet is studied in this paper. Two improved techniques, namely adaptive weighting quantization combining with famous SPHIT and fast wavelet transform based on lifting scheme, are proposed for two typical remote sensing image compression respectively. Experiment shows that our improved ways are effective for remote sensing image compression. |

| Keywords: | Wavelet transform Remote sensing image compression Zero tree quantization Lifting scheme |
