[16] How does JPEG work?
Technical details are outside the scope of this FAQ, but you can find
an introduction and references for further reading in the comp.compression
FAQ, which is available from http://www.faqs.org/faqs/compression-faq/
(See [23] Where are FAQ lists archived?).
The comp.compression FAQ is also a good starting point for information on
other state-of-the-art image compression methods, such as wavelets and
fractals. A quick comparison: wavelets are likely to be the basis of the
next generation of lossy image-compression standards, but they are perhaps
10 years behind JPEG in the standardization pipeline. Fractals have been
terribly over-hyped by their chief commercial proponent, and seem to be
losing favor as people learn more about their true capabilities.
