针对航空侦察图像的原始分辨率高，且在存储过程中必须进行无损或者近无损图像压缩的问题，为满足任务判读的要求，实现实时高效的数据压缩处理具有重要的工程价值。本文首先比较了几种无损或者近无损图像压缩的硬件平台，然后介绍了JPEG标准族的无损/近无损图像压缩的算法框架和不足，最后阐述了最近刚正式问世的新一代JPEG XR图像压缩标准，并指出了JPEG XR标准的优势所在。

In order to meet the increasingly higher image resolution requirements in aviation reconnaissance as well as lossless and near-lossless image compression in storage process,it is important to realize fast and efficient compression to satisfy the various requirements in mission interpretation. First, we review several basic platforms applied to lossless and near-lossless image compression, and then we introduce the lossless or near-lossless encoders’diagrams of JPEG standard series and point out their respective flaws. Finally, after a summary of current works on JPEG XR standard, the advantages of JPEG XR are given.
