Method

Description

Implementation

Random

The initial cluster means are selected at random

RGB and CIELab

Uniform Linear

The initial cluster means are selected uniformly along the line defined by [0 0
0] and [1 1 1].

RGB only

Uniform Cube

The initial cluster means are selected uniformily throughout the the RGB cube defined
by [0 0 0] and [1 1 1]. This only works for segmentations where the cube root of
the number of clusters is is a positive integer greater than one. There is a special
exception for the case when number of clusters is nine.

RGB only

Statistical

The initial cluster means are selected uniformly along the line defined by mean
of the samples minus one standard deviation and the mean of the samples plus
one standard deviation.
