# `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:

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

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