Detailed Description

template<typename T, typename I = T>
class SourceXtractor::FunctionalImage< T, I >

Apply a transformation to each individual pixel

Template Parameters

T	Pixel type
Pixel	type of the input image

Warning

Make sure the functor does not capture anything that may be outlived by the functional image. This is hardly surprising. Also, make sure that whatever is captured is thread safe!
