title: How to Create CaffeDB training data for siamese networks out of image directory
body: <p>I need some help to create a CaffeDB for siamese CNN out of a plain directory with images and label-text-file. Best would be a python-way to do it.<br>
  The problem is not to walk through the directory and making pairs of images. My problem is more of making a CaffeDB out of those pairs.<br>
  So far I only used <a href="https://stackoverflow.com/a/31431716/1714410"><code>convert_imageset</code></a> to create a CaffeDB out of an image directory.<br>
  Thanks for help!</p>
