问题描述
任何人都可以指导我使用C / C ++进行非常好的一维DCT实现
我的数据是成套的8个数字。
非常感谢，
Soumyadip。
Hi,
Could anyone direct me to a very good 1D DCT Implementation in C/C++
My data is in sets of 8 numbers.
Thanks a ton,
Soumyadip.

这应该是显而易见的1D DCT是什么？我不记得它是用语言本身定义的
。你是在正确的新闻组吗？

Is it supposed to be obvious what "1D DCT" is? I don''t remember its being
defined in the language itself. Are you in the right newsgroup?

对不起，我的意思是一维离散余弦变换。

Sorry, I meant 1-Dimensional Discrete Cosine Transform.

您可以扩展在线程中找到的DFT（下面）。 Bux先生
彻底检查了我的DFT版本，这非常棒。我意识到你
不在乎它是否是C与C ++，但我有点厌恶所有C / /
版本的transfrorms我'见过（所有malloc'，免费'让我
紧张）。

旁白：我怀疑你可能正在改变图像数据？在那个
方面，DCT可以通过DFT进行后旋转
You could expand on the DFT found at the thread (below). Mr Bux
overhauled my version of the DFT and it''s excellent. I realize you
don''t care if it''s C versus C++ but I''m sort of sick of all the C
versions of transfrorms I''ve seen ( all the malloc''s, free''s make me
nervous ).

An aside: I suspect you''re probably transforming image data? In that
regard, the the DCT can be performed by a DFT with a post-rotation
