Abstract :
The hyper-spectral image compression is one of the front technologies in the remote sensing. The hyper-spectral image has enormous data quantity, so it is important to research on the hyper-spectral image compression. Based on the spectral LOCO-I prediction algorithm, the hyper-spectral image compression system is completed with the DSP+CPLD technology. The result shows that the system can compress the image with a higher compression ratio and is faster than processing image under the PCs and has certain practicability.
