Detailed Description

A segmentation algorithm which is based on a color-quantization algorithm followed by a smoothing filter.

The quantization of the colors is done with the k-Means algorithm, which creates an optimal color-palette, to which all original image colors are mapped to. The smoothing filter (None, Median, K-Nearest, ...) can be choosen with the parameters objects.
