title: How does shift-and-stitch in a fully convolutional network work?
body: <p>I am still struggling with the "shift and stitch" trick in <a href="https://people.eecs.berkeley.edu/~jonlong/long_shelhamer_fcn.pdf" rel="nofollow noreferrer">FCN</a> after repeating reading it many times. </p>
  
  <p>Can someone give some intuitional explanation?</p>
