Question

英语翻译
Without quality degradation in the important image areas
a compression of 1:50 - 1:80 can be achieved with the
multi-resolution method compared to the compression of
1:20 - 1:30 with use of JPEG only.
1:50 - 1:80 ...是表示压缩的程度吗?

Answer 1

如果保证重要画质部分没有损失,那么相对于JPEG 1:20 - 1:30 的压缩比,有多种方法可以获得1:50 - 1:80 的压缩比.
