JPEG2000 still image compression standard accessed to people’s attention because it has many excellent features. It took the embedded block coding with optimal truncation (EBCOT)and discrete wavelet transform technology(DWT) as the two main technologies. So it has a higher compression ratio for large-size images and a flexible compressed stream compared with the JPEG standard.We introduced
