ipvi

eolab.georastertools.processing.algo.ipvi(bands: ndarray) → ndarray[source]

Compute the Infrared Percentage Vegetation Index of the input data. The coefficient ranges from 0 to 1 in each pixel.

The function considers the bands of the input data in the following order : Red, NIR (Near Infra-Red).

\[IPVI = \frac{NIR}{NIR + RED}\]

Parameters:: input_data (np.ndarray) – Numpy array of 3 dimensions (number of bands, number of lines, number of columns) with number of bands > 1.
Returns:: Numpy array of size (number of lines, number of columns) containing the computed IPVI.
