title: How to read the data of Adience benchmark(data set for gender and age classification)?
body: <p>I am trying to train a gender and age classification by cnn, using the data at  <a href="http://www.openu.ac.il/home/hassner/Adience/data.html#frontalized" rel="nofollow noreferrer">adience</a> and I got two questions.</p>
  
  <p>1 :  According to the website, the bounding box of the faces are recorded in the fields "x,y,dx,dy". As an example, from fold_frontal_0_data.txt,the first data is</p>
  
  <pre><code>image name  : 10424815813_e94629b1ec_o.jpg  
  (x,y,dx,dy) : 301 105 640 641   
  </code></pre>
  
  <p>However, the data of the bounding box is weird, because the size of the image is 600x601 only, no matter I treat (x,y,dx,dy) as (left, top, width, height) or (left, top, right, bottom), I cannot crop the face as expected. How could I crop the face properly?</p>
  
  <p>2 : Do I need to do face alignment on training data? Or I only need to do face alignment when testing?Or both?Thanks</p>
