Avoid multiple for loops, use inbuilt imfilter function for masking operation.

The concept is same in all images. For image enhancement you can perform numerous operation depends on input image.

%arithmetic mean filter
im=rgb2gray(imread('chest.tif'));
h=fspecial('average',3);
filter_image=imfilter(im,h);

          x(i,j) = x(i,j) <= 5
      else if j==2
          x(i,j) = x(i,j) <= 15
      else 
          x(i,j) = x(i,j) <= 25
      end
  end
end
