So the ISO referred the new still image compression standard: JPEG2000. This paper first introduced the theory of still picture standard JPEG2000 and discussed the key techniques .

为此，国际标准化组织（ISO）指定了新一代静止图像压缩标准：JPEG2000。 该文首先阐述了JPEG2000图像编码系统的实现过程，对其中的关键技术做了详细描述。

So, the compressed picture than before reduced about 10 times, and the compressed image quality basic no change, lossless compression.

左右，压缩后的图片比之前缩小了10倍左右，而且压缩后的图片质量基本没什么变化，实现无损压缩。

The still image compression mentioned in the article is a strategy of VQIC that is based on analyzing the composition of a picture.

该文所叙述的方法，就是在JPEG格式的基础之上，通过简单分析被处理图像的构图来策略性地配置图像中重要性不同区域的不同压缩比。
