====== atCluster ====== ===== Plugin information === ^ Author: | Aaron | ^ Description | An experimental plugin for performing k-means clustering of RGB image files. This can be useful as a pre-filter for [[plugins:fileio:atimportam|importing attributes maps]]. | ^ Menu option | '//Extensions->atCluster->Cluster image//' | ^ Download link | [[http://www.bundysoft.com/L3DT/downloads/plugins/bin/atCluster-bin.zip|atCluster-bin.zip]] [140kB] | ^ Last update | 31 May 2015; v15.5.0.1 | ^ How to install? | Please refer to the [[bundydocs>l3dt:userguide:extensions:install|plugin installation guide]]. | ===== Using atCluster ===== This is an experimental plugin. The user interface is still //very// basic. Not recommended for production environments. ==== Clustering an image to make an attributes map ==== - Select '//Extensions->atCluster->Cluster image'//. - Select an import image. - Enter settings * //nClustersMax// is the maximum number of clusters to be found. If importing for an attributes map, keep this small (<< 100). * //nIterationsMax// is the maximum number of iteration cycles in the k-means algorithm. 10 is recommended. - //atCluster// will then cluster the image and export a file called '[orignal file name]_clustered.bmp'. This file should look the same as your input image, but with slightly 'stepped' colours. This output image will only contain a small number of unique colours (as given by //nClustersMax//), which should be suitable for importing as an attributes map. - Select '//Import->Attributes map->Import from colour map//', and follow [[plugins:fileio:atimportam#using_atimportam|this guide]]. Please note that you will need to manually assign climates/land types to the colours in the image. ===== Changes ===== 2015/05/31 06:07 --- Released v15.5.0.1.
