The problem with using Deconvblind to deblur the image

Hello everyone,

Now I try to use Deconvblind command to deblur the image of nanoparticles. But the deblur image is very weird, the centroid of imaging of nanoparticle is black. Does anyone know the reason of it? Sorry, I don't know how to upload the image of nanoparticle.

The codes are show below: clear; clc; I = imread('C:\image\Au.png'); subplot(121);imshow(I) PSF = fspecial('gaussian',7,10); [J1 P1]=deconvblind(I,PSF); subplot(122);imshow(J1);

I don't have your image so I can't see or experiment. You probably chose the wrong size filter and you're getting ringing. Try changing your filter size.
