Colour Clustering Functions

Cluster

Returns the input image represented in the user specified number of colours. The colours are automatically chosen so as to minimise the error between the input and output images

SICluster

Returns the input image represented in a fewer number of colours, which is automatically determined so as to minimise the error between the input and output images. The starting number of colours is 32. A second image is also returned containing colour numbers rather than the colours themeselves
