 [i,j]=find(mask);

rgb=imread(input_img_path);
  
   
       for k=1:numel(j)
        
rgb(i(k),j(k),1:3)=mean(x=[rgb(i(k)-1,j(k),1:3),rgb(i(k)-1,j(k)-1,1:3),rgb(i(k)-1,j(k)+1,1:3),rgb(i(k),j
  
(k)-1,1:3),rgb(i(k),j(k)+1,1:3),rgb(i(k)+1,j(k)-1,1:3)
,rgb(i(k)+1,j(k),1:3),rgb(i(k)+1,j(k)+1,1:3)]);
        
      endfor


i have a mask with "wrong" pixels of a photo and i want to repair this
photo, replacing the value of "wrong" pixels with avrage of points around.
there are not 2 "wrong" pixels joined, one next to another. 
i want to to this without "for" for better speed
