RVI
(Radar Vegetation Index)ΒΆ
This functionality computes the radar vegetation index for dual polarimetric (HH | HV), (VV | VH) SAR data. The required input and the computed output are as follows:
input : input_c2_folder, window_size
output: RVI_dp.bin
The formulation of RVI is as follows:
\[\text{RVI}_{dp} = \frac{4 \times \sigma^\circ_{\text{XY}}}{\sigma^\circ_{\text{XX}}+\sigma^\circ_{\text{XY}}}\]
where, \(\sigma^\circ_{\text{XX}}\) is co-pol backscatter intensity and \(\sigma^\circ_{\text{XY}}\) is corss-pol backscatter intensity
