MATLAB: PSF (Motion blur) from the blurred and sharp (or deblurred) image pair.

digital image processingimage deblurringimage processingpsf

There are works which finds PSF and deblurred image when only blurred image is given (Blind deblurring).
Is there somebody who knows any technique to find PSF given blurred and the original sharp image (extra information) to which that PSF got applied to get the blurred image.
ie. PSF from blur-sharp pair (blur=PSF*sharp)

Best Answer

In frequency domain, PSF can be calculated as fft(blurred)/fft(original).
