Is it gray scale or color? And this seems to be the hot topic of the month. There are so many threads lately on manually computing blurring or filtering of images with nested for loops - just search for them. I'm attaching my demo.

A convolution may be what you need.
mask=rand(3,3);mask=mask/sum(mask(:));
IM=uint8(randi(255,100,100));
IM2=convn(IM,mask,'same');

@magramane khadidja, it's still showing you as not having posted a question of your own (in a new thread like I asked). Where is it? What's the link? Over there, give your code with the functions I listed, and attach your image.
