数学原理不需要搞清. 能够通过这,

开始写自己的编码/解码程序. 或者看懂以有的代码. 对有损图形压缩有进一步了解.

自己能够改良 JPEG, 比如增加透明色的支持, 加快 JPEG 的解码速度.-Do not need to gain a clear understanding of mathematical principles. Can begin to write their own encoding/decoding process. Or understand to some code. To undermine the further understanding of graphics compression. They can improve the JPEG, such as increased support for transparent color, speed up JPEG decoding speed.
