This tab allows for the :ref:`clustering_definition` of a :ref:`band_set_tab`. In particular, :ref:`kmeans_definition` method is available.
The spectral signatures are saved along with the classification, and can be saved in the :ref:`training_input`.

select one options for seed signatures that start the iteration; the option :guilabel:`Seed signatures from band values` divides the spectral space of the :ref:`band_set_tab` to get spectral signatures; the option :guilabel:`Use Signature list as seed signatures` uses the spectral signatures checked in :ref:`ROI_list`; the option :guilabel:`Use random seed signatures` randomly selects the spectral signatures of pixels in the :ref:`band_set_tab` |
| :guilabel:`Distance algorithm`
:guilabel:`Minimum Distance`
:guilabel:`Spectral Angle Mapping` |
select :ref:`minimum_distance_algorithm` or :ref:`spectra_angle_mapping_algorithm` for spectral distance calculation |
| :guilabel:`Save resulting signatures to Signature list` |
if checked, save the resulting spectral signatures in the :ref:`ROI_list` |
:guilabel:`Script`  |
add this function to the :ref:`script_tab` |
:guilabel:`RUN`  |
run this function |
