SAGA.imagery_classification.1: K-Means Clustering for Grids

This tool implements the K-Means cluster analysis for grids in two variants, iterative minimum distance (Forgy 1965) and hill climbing (Rubin 1967).

Inputs

Grids

format
href
Please set a value for GRIDS.

Method

string

Number of clusters

integer

maximum number of iterations, ignored if set to zero (default)

integer

Automatically normalise grids by standard deviation before clustering.

boolean

Use the first three features in list to obtain blue, green, red components for class colour in look-up table.

boolean

Start Partition

string

slower but memory saving
