.. automodule:: pysptools.eea

Endmembers Extraction Algorithms (EEA)
**************************************

This module Supports following endmembers extraction algorithms:

* `Automatic Target Generation Process (ATGP)`_
* `Fast Iterative Pixel Purity Index (FIPPI)`_
* `N-FINDR`_
* `Pixel Purity Index (PPI)`_

.. seealso:: See the file :download:`test_eea.py<../../tests/test_eea.py>` for an example.


.. note:: Regarding the *normalize* parameter, if you have data that are out of bound in your HSI cube, the use of *normalize* is not recommended. You must clean up the data before using this parameter.
