This is my current code:
function newImg = adjust_img(current_img)
for current_img>255
new=255;
newImg=new;
end
for current_img<0
new=0
newImg=new
end

newImg = max(0, min(255, current_img));
after which you will probably want to uint8() the result which would probably otherwise be class double()
On the other hand if you are going to uint8() the result of the above, you could replace the whole thing with
newImg = uint8(current_img);
as uint8() will make any negative values into 0 and make anything over 255 into 255.
