| NeuQuantOpImage | | public class NeuQuantOpImage extends ColorQuantizerOpImage (Code) | | An OpImage implementing the "ColorQuantizer" operation as
described in javax.media.jai.operator.ExtremaDescriptor
based on the median-cut algorithm.
This is based on a java-version of Anthony Dekker's implementation of
NeuQuant Neural-Net Quantization Algorithm
NEUQUANT Neural-Net quantization algorithm by Anthony Dekker, 1994.
See "Kohonen neural networks for optimal colour quantization"
in "Network: Computation in Neural Systems" Vol. 5 (1994) pp 351-367.
for a discussion of the algorithm.
