I would like to see how MTF blurs an image for my academic works. I will load the original image and I will have an MTF value (for example MTF=0.7), then I would like to have blurred image that is the result of the original image and MTF interaction. I appreciate it if anyone could give me a script or method suggestion.
Thanks in advance,

Use fspecial() to create Gaussian PSF's, which is just the spatial domain representation of the MTF. Then pass the PSF into imfilter().

The MTF is 1 at the zero frequency. You vary the sigma according to how much you want it to cut off the higher frequencies.
