◆ dither()

template<class VTIn , class VTOut >

double HuginBase::Photometric::InvResponseTransform< VTIn, VTOut >::dither ( const double & v ) const

Dithering is used to fool the eye into seeing gradients that are finer than the precision of the pixel type.

This prevents the occurence of cleanly-bordered regions in the output where the pixel values suddenly change from N to N+1. Such regions are especially objectionable in the green channel of 8-bit images.
