One simple examle to estimate the NDVI and DVI from the R, G, NIR, SWIR data.
>>> from vilib.vilib import vi >>> g = np.random.randn(100) >>> r = np.random.randn(100) >>> nir = np.random.randn(100) >>> swir = np.random.randn(100) >>> foo = vi(g,r,nir,swir) >>> ndvi = foo.get_vi('ndvi') # calculate the NDVI >>> dvi = foo.get_vi('dvi') # calculate the DVI
