I should set the record straight by saying that, as far as I know, the Utah Raster Toolkit is the only package that incorporates my code. The credit for "fbquant" and whatever is implemented in piclab goes to their respective authors. The code I wrote, "colorquant", implements the algorithm described in: Wan, Wong, and Prusinkiewicz, An Algorithm for Multidimensional Data Clustering, Transactions on Mathematical Software, Vol. 14 #2 (June, 1988), pp. 153-162. Colorquant is available via anonymous ftp from weedeater.math.yale.edu as pub/colorquant.shar. The Utah Raster Toolkit is available from weedeater.math.yale.edu, freebie.engin.umich.edu, cs.utah.edu, and other archives sites.
