title: Train TensorFlow to modify images
body: <p>I am interested in the possibility of training a TensorFlow model to modify images, but I'm not quite sure where to get started.  Almost all of the examples/tutorials dealing with images are for image classification, but I think I am looking for something a little different.</p>
  <p>Image classification training data typically includes the images plus a corresponding set of classification labels, but I am thinking of a case of an image plus a &quot;to-be&quot; version of the image as the &quot;label&quot;.  Is this possible?  Is it really just a classification problem in disguise?</p>
  <p>Any help on where to get started would be appreciated.  Also, the solution does not have to use TensorFlow, so any suggestions on alternate machine learning libraries would also be appreciated.</p>
  <p>For example, lets say we want to train TensorFlow to draw circles around objects in a picture.</p>
  <p>Example Inbound Image:</p>

  <p>Label/Expected Output:</p>

  <p>How could I accomplish that?</p>
