In the context of trying to use StarNet++ on linear images, I have seen some recommendations to temporarily stretch the image with mtf(m), and then after running StarNet++, to reverse the stretch with mtf(1-m). This does not seem to exactly invert the function.
Is there a mathematically exact way to invert mtf()?
