基于JPEG2000的遥感图像分级量化压缩

Sub-band Quantification Compression of Remote Sensing Image Based on JPEG2000

介绍了JPEG2000静态图像压缩标准的基本情况;对遥感图像的相关性以及小波变换域统计特性进行了分析,得出遥感图像的特点。针对其特点,设计了基于JPEG2000无损压缩的高频子带分级量化高保真压缩方案。实验结果表明,此方案在对遥感图像进行压缩时取得了较好的效果。

The JPEG2000 still image compression standard is introduced.The similarity and statistical characteristics in wavelet transform field of remote sensing image are studied.Based on the characteristics,a high frequency sub-band quantification scheme of compression based on JPEG2000 is proposed.Experimental results show that the scheme attains good quality.
