Section - [17] 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 also "[24] 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 and limitations. |
