Hi, I cannot get the output of this code, I don't understand where problem is. Thank you
I=imread('Desktop/mak/exp.jpg');
isp=imnoise(I,'salt & pepper' 0.1);
a=fspecial('average');
a1=filter2(a,isp);
figure,imshow(uint8(a1));

I think several points should be checked:
  1. File path in the line 1 is correct?
  2. 3rd input argument of imnoise function should be separated by ','
  3. imfilter function should be used in th eline 4, instead of filter2 function
  4. uint8 in the last line can be deleted
The following is an example.
I = imread('exp.jpg');
isp = imnoise(I,'salt & pepper',0.1);
a = fspecial('average');
a1 = imfilter(isp,a);
figure;imshow(a1);
