  Modulation transfer function (MTF)


The Modulation Transfer Function (MTF) represents the response of an imaging system to an input signal of continuously varying spatial frequency.  Modulation of a signal is defined as
 
Modulation (M) = (I(max) - I(min))/(I(max) + I(min))
 
where I(max) is the maximum intensity of the signal (e.g. white in grey scale image) and I(min) is the minimum intensity (e.g. black in grey scale image).  This can also be interpreted as the total contrast of the im...
