摘要
对ＫＬ－变换（ＫＬＴ）／ＪＰＥＧ和ＪＰＥＧ／ＫＬＴ构成的多光谱图象数据压缩系统的性能及优缺点进行了分析比较。在充分利用多光谱图象数据统计特征的基础上，将ＫＬＴ应用于多光谱数据压缩系统来消除谱相关性。仿真实验结果表明。
The compression performance,advantage and disadvantage of KL transforms(KLT)/JPEG and JPEG/KLT for multispectral image data are presented.On the basis of statistical properties of multispectral image used,KLT is applied in the multispectral data compression system to remove spectral correlation. Simulation experiment results show the total performance of KLT/JPEG compression system is superior to that of JPEG/KLT compression system.
