Notice that, with modern compression techniques such as JPEG 2000, the total size of the image can be easily divided by 50 without losing a lot of quality, but this is another topic.

注意，与现代压缩技术例如JPEG 2000年，图象的总规模可以容易地除50，无需丢失很多质量，但是这是另一个题目。

On the basis of understanding all kinds of ceding techniques, the system choose DCT technique.

在进行变换域系数编码中，考虑到空间图象传输中信道噪声的影响，本系统没有采用一般压缩编码中常用的Huffsman编码，游程编码和DPCM技术，而是选用了区域编码，分配固定比特的方法，经过分析这种方案的抗噪声能力较强。
