Image Processing and MatLab (Deconvolution Process)

  1. Nov 5, 2015 #1
    I have these two images:

    Blurred_Image01.png Blurred_Image02.png

    And I have this impulse response function, or the point-spread function (PSF):

    Sample_PSF01.png Sample_PSF02.png

    The first image is the actual size of the PSF, and the second image has zero pads included.

    I tried deconvolving the images this way (with MatLab):

    Code (Text):
    deconvolved_image = ifft2(fft2(blurred_image)./fft2(sample_psf))
    The PSF that I used is the PSF with zero pads. However, the deconvolved images are different. The deconvolved image of the first blurred image is correct and I achieved a sharp image, however the second one returns this image:


    What could be wrong?

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
