I have two images, one blurred and another sharp image. I need to recover the original image using these images. I have used simple FFT and inverse FFT to estimate point spread function and deblurred image.
fftorg = np.fft.fft2(img1)
fftblur = np.fft.fft2(img2)
psffft = fftblur/fftorg
psfifft = np.fft.ifftshift(np.fft.ifft2(psffft))
plt.imshow(abs(psfifft), cmap='gray')
This is the point spread function image I got, I need to find the type of kernel used for blurring and also its size. Is it possible to get the kernel used from PSF?
