摘    要:遥感影像的内容十分复杂,分辨率较高,用于电视图像或其它视尖信号的无损压缩方法很难使遥感影像的无损压缩达到2倍的压缩比。本文提出一种遥感影像的无损压缩方法,用该方法可使大部分遥感影像达到2倍以上的压缩比。最后还对这部分影像用小波分解理论进行分析,得到0这部分影像量的特征。

关 键 词:图像压缩  信源编码  波变换  遥感

Abstract:The contents of remote sensing images are very complicated and with high resolution. So the lossless compression ratio(CR) of these images is hardly higher than 2 using methods suitable for TV images and other video signals. This paper provides a lossless compression scheme by which the CR can be greater than 2 for most parts of these images. Finally, on the basis of analysis using wavelet transform, we have got guantitative characteristics of these images.
Keywords:Image compression  Source coding  Wavelet transformation
