im looking for a simple source can help me to understand the DFT(direct fourier

transform) in the sequential jpg image compressor, im little weak in this kinds of

mathematics, but unfortunatly its essential to be good using fourier transform to

understand the whole copression idea.
 

The transformation used in JPEG is DCT not DFT.
The mathematics are described in DSP-like book.
If you want to know the idea of lossy compression,
you can read the books titled "data compression" ,"source coding", etc....

Regards,
Jarod
