Abstract :
An optimized JPEG2000 compression algorithm based on DSP platform was brought forward to meet the critical quality requirement of the international standard of VDR. System architecture of radar image capture and compression system is presented first. Two new techniques to handle calculation error and irrational number of normalization factor in LS (9, 7) were explained in detail and the test result of them was shown. Finally, three levels of JPEG2000 algorithm transplantation and optimization based on DSP platform are listed.
