[jira] Commented: (MAHOUT-517) Eigencuts needs an output format

["Shannon Quinn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12917859#action_12917859 ] 

Shannon Quinn commented on MAHOUT-517:
--------------------------------------

In the literature, since this algorithm was originally devised for clustering in images, the output was always a segmented image - not really something Mahout is meant to do without adding more dependencies. Still, something along the lines of KMeans - using pixel coordinates (or ranges) instead of raw values - might be useful.
