[comp.graphics] Question on Octree Colour Quantization

marcos@netcom.UUCP (Marcos H. Woehrmann) (11/28/90)

I'm interested in hearing from anyone who has implemented the Octree
colour quantization algorithm from "Computer Gems" (p. 287).  
 
I've gotten it working; but the my implementation gives poor results
for certain types of images (in particular those images which contain
lots of minor variations of a few different colours).  Is this an
inherent flaw in the method, or have I chosen my octree reducing
criteria badly?
 
Please send mail;  if enough people are interested I'll summarize.
