Public Methods

Method	Description
Map ( int b, int g, int r ) : int	Search for BGR values 0..255 (after net is unbiased) and return color index.
NeuQuant ( byte thePic, int len, int sample ) : System	Initialise the quantization process in range (0,0,0) to (255,255,255).
Process ( ) : byte[]	Starts the quantization.

Private Methods

Method	Description

Altersingle ( int alpha, int bestBias, int b, int g, int r ) : void	Move neuron (bestBias) towards biased (b,g,r) by factor alpha.
ColorMap ( ) : byte[]
Contest ( int b, int g, int r ) : int	Search for biased BGR values.
Inxbuild ( ) : void	Insertion sort of network and building of _netindex[0..255] (to do after unbias).
Learn ( ) : void	Main Learning Loop.
Unbiasnet ( ) : void	Unbias network to give byte values 0..255 and record position to prepare for sort.
