``DOP`` (Degree of Polarization)
=================================
This functionality computes the 3D Barakat degree of polarization for full polarimetric SAR data. The required input and the computed output are as follows:

.. code-block:: python

    input : input_T3/C3_folder, window_size
    output: DOP_FP.bin

.. math::

    \text{DOP}_{fp}=\sqrt{1-\frac{27\times\text{det([T3])}}{\text{(Trace[T3])}^3}}

Further details on the Barakat Degree of polarization can be found in [[10]](#10)
