C# Class ScreenToGif.ImageUtil.Quantitizer.NeuQuant.NeuralColorQuantizer

The NeuQuant Neural-Net image quantization algorithm (© Anthony Dekker 1994) is a replacement for the common Median Cut algorithm. It is described in the article Kohonen neural networks for optimal colour quantization in Volume 5, pp 351-367 of the journal Network: Computation in Neural Systems, Institute of Physics Publishing, 1994 (PDF version available).
