What is the equation for MTF?
The MTF, or Modulation Transfer Function, is defined as the ratio of the image contrast to the target contrast, expressed as a function of spatial frequency. That is, MTF(u) = C'(u) / C(u). C is the contrast in the target, C' is the corresponding contrast in the image.
What is the MTF contrast equation?
A higher MTF value indicates better image quality and resolution. It is analogous to a high-resolution TV versus a pixelated low-resolution screen. The MTF is the ratio of relative image contrast divided by relative object contrast: Modulation transfer function = relative image contrast/relative object contrast.
What is MTF in image quality?
The modulation transfer function, or MTF, is a parameter used to evaluate the performance of a lens. MTF provides a quantitative and standardized way to characterize optical systems, so the metric is used by optical designers and microscopists alike to compare lenses and determine the ideal one for an imaging system.
Why slanted edge MTF?
The slanted-edge method specified in ISO Standard 12233, which measures the modulation transfer function (MTF) by analyzing an image of a slightly slanted knife-edge target, is not robust against noise because it takes the derivative of each data line in the edge-angle estimation.
"""Computes the MTF50P value of an edge. This function implements the slanted-edge MTF calculation method as used in. the Imatest software.
