Detailed Description

template<class VT1, class LUT>
struct vigra_ext::InvLUTFunctor< VT1, LUT >

functor to apply a LUT to gray and color images.

This functor works by using a binary search and does linear interpolation.

floating point values between 0..1 are mapped to min and max of the lookup table.

integers are also mapped to 0..1 before applying the lut.
