Optimal palette

[Borneq]

We have an RGB image. How can choose fro example 16 or 256 or another
number of colours such that palette image is maximal similar to RGB image?

Hi,

I hve tried using a pairwise clustering algorithm with good results.
The papers I found were:

Color quantization by pairwise clustering using a reduced graph 2001

Color Image Quantization by Pairwise Clustering

The second ond compared Uniform, Popularity, Median Cut, Local K-means,
Varience Based, Octree, and Pairwise Cluster algorithms.
