| Abstract: | This paper introduces an application of JPEG2000 image code algorithms to achieve radar image capture and compression systems,have explained the hardware realization platform about radar image capture and compression system first,and proceed to concentrate on explaining the JPEG2000 compression algorithm,preprocessing,discrete wavelet transform,embedded block coding with optimal truncation this three big essentials having explained detailed in JPEG2000 coder,have given out corresponding procedure flow chart.Have explained that the JPEG2000 algorithm arrives at DSP transplanting and optimization from PC again.Have given out the performance test of the radar image capture and compression systems finally. |
