title: Haar Lifting scheme
body: <p>I am trying to apply lifting scheme version haar to an image. I started to apply it using the code posted on the internet:</p>
  
  <pre><code>   image = imread('cameraman.tif');
     % Applying Lifting scheme
     lshaar = liftwave('haar');
     els = {'p',[-0.125 0.125],0};
     lsnew = addlift(lshaar,els);
     [cA,cD] = lwt(image,lsnew);
  </code></pre>
  
  <p>In fact the code above apply a lifting Haar wavelet of LEVEL1. How can I modify this code in order to apply 2 or 3 levels of lifting Haar wavelet?</p>
  
  <p>Any help will be very appreciated!</p>
