| Abstract: | As a new standard of image compression,JPEG2000 provides a set of higher performance as well as new features.To address the applications of JPEG2000 in mobile area,this paper studies the key techniques about the implementation of JPEG2000 based on DSP after analyzing the JPEG2000 coding process.And tests have now been carried out which reveal that the coding algorithms of JPEG2000 are successfully implemented on DSP. |
