Modulation
Transfer Function
The Modulation Transfer Function ( MTF ) of an imaging system is a
measure its ability to resolve detail within the image. The MTF is
usually represented as a graph and plots the Modulation Transfer
Factor ( Mu) over a range of spatial frequencies (u), Where the
Modulation Transfer Factor represents the percentage change of
modulation at each spatial frequency.
