I have a image of 199x199 and I want to deblur/sharpen this image

I have tried imsharp, deconvlucy but they're not working as expected

PSF = fspecial('gaussian',5,5);
luc1 = deconvlucy(noisy_img,PSF,5);
imshow(luc1,[])

figure;
imshow(nosiy_img,[]);
I_sharpen=imsharpen(nosiy_img,'amount',10);
figure;
imshow(I_sharpen,[]);
title('Sharpened Image');
g=fspecial('average',[10,10]);
g=imfilter(nosiy_img,g);
g=3*imsubtract(nosiy_img,g);
figure,imshow(g,[]);
x=imadd(nosiy_img,g);
figure; imshow(x,[]);

Hi Shubham,

As I can understand from your question, you have already tried out some deblurring algorithms, but your results were not satisfactory.

To get an enhanced image from a blurry image requires extracting several information from an image and using that information to further enhance it. You can use this resource to use blind deconvolution to deblur images.

Hope this helps.
