inlineoverridevirtual

Astract method which will compute the radiometric indice

Parameters

input

A itk::VariableLengthVector<TInput> holding the pixel values for each band

Returns

The indice value as TOutput (starts at 1 for first band)

Implements otb::Functor::RadiometricIndex< TInput, TOutput >.
