 We're due to release GIMP 1.2 in the near future. It's a little bit to
 late to introduce a new quantization algorithm right now. With GIMP 2.0
 we'll have the chance to let advanced user choose his preferred algorithm...

Color Quantization

[Martin Weber]

The aim of GIMP is not only to be as good as Photoshop but become better
than this program. So it would be fine to implement features that even
commercial programs don't have. The common color quantization algorithms
have many disadvantages, but there is a very new called Spatial Color
Quantization (http://www-dbv.informatik.uni-bonn.de/quant/) that is
better than all other methods. Is there anyone who has enough time to
implement this very good algorithm.

Color quantization

[Martin Weber]

Benny's Wu quantization is very good (http://www.geocities.com/SiliconV
alley/Program/8979/color/index.htm)
Can anyone help to improve the speed of it?

Martin

PS: Perhaps it could be faster than GIMP's
