[Insight-users] clustering/segmentation

[Luis Ibanez]

Hi Zein,


In order to Cluster/Classify/Label pixels in a
multiband image you may want to take a look at
the following methods:



1) ImageKMeansModelEstimator
http://www.itk.org/Doxygen/html/classitk_1_1ImageKmeansModelEstimator.html
which performs clustering. This one is optimized for Images.


2) KdTreeBasedKmeansExtimator
http://www.itk.org/Doxygen/html/classitk_1_1Statistics_1_1KdTreeBasedKmeansEstimator.html
which also performs Kmeans clustering but using a generic
KdTree structure. An image can be adapted to this generic structure.


3) The MRFImageFilter
http://www.itk.org/Doxygen/html/classitk_1_1MRFImageFilter.html
Which labels an image using a Markov Random Fields approach and
MAP (maximum a posteriory) optimization.


4) KLMRegionGrowingImageFilter
http://www.itk.org/Doxygen/html/classitk_1_1KLMRegionGrowImageFilter.html
Which minimizes an energy potential computed over regions and
boundaries.


Please let us know if you have further questions.



   Thanks


    Luis
